Unlike DOS, Windows is a multi-tasking environment. Therefore, if you
have many programs running at once, each will run slower. (You can, if you want, apportion the CPU time unequally among them.) However, as far as I can tell, the total time it takes for all of them to do their calculations isn't inherently slower with Windows than DOS. Windows-based antenna simulation programs are no different than other Windows applications. When running in "DOS mode" (under Windows systems prior to XP -- it's not available in XP), you are running in a true, single-tasking DOS environment. This is the mode you have to boot separately into when starting the computer. But if you choose the "DOS prompt" (or "command prompt") while running Windows, you're really running in the full Windows environment, and emulating DOS as just another Windows task. Programs running in this mode can't run any faster than a normal, native Windows program, since they're also subject to the time sharing of the multi-tasking system. There might actually be some additional overhead from the emulation process. The first Windows version of EZNEC, v. 3.0, ran calculations about 20% faster than the DOS version, possibly due to a compiler change. There was certainly no major slowing down of the calculations due to the different operating system. The current version of EZNEC, v. 4.0, runs up to several *times* faster than that due to code changes. Roy Lewallen, W7EL wrote: . . . On a side note with respect to some computors slowing down. Are the Windows based computor programs with respect to antenna modelling also subject to overload or slowing down problems or are they some how immune to the described problems? . . . |

Believe it or not I understand what you have posted so the info you have provided will be good news to antenna modelers. I really do not know how my personal antenna program works except I have a small disc inserted that when I start the computor I have to press the F12 key when prompted and somehow it does not display the normal windows entry but goes straight into a DOS managed antenna modeler program. I suspect that the disc somehow partitions the Dos emulator from the windows program and makes it a seperate entity in a similar way that previous widows programs did before they were bundled together.When I model closely coupled antenna elements designs where one has to make it 80 segments a shot a slow down of the coprocessor would be unacceptable Regards Art "Roy Lewallen" wrote in message ...

I have found that it renders everything very closely to IE and FireFox. Some minor differences but nothing great. FYI, I have IE6, with Service Pack 2 (for XP Home Edition), and that includes a Microsoft pop-up blocker. It works better than StopZilla's blocker, and it's free. Bob k5qwg |

Bob k5qwg I also have IE6, but I run XP Pro with Service Pack 2. I have not found that the Microsoft pop-up blocker is better. I hit a site, a couple of months ago. Before I connected, my counter was around 900 popups blocked. The next time I looked at it, it was 9,000 popups blocked. I didn't even notice a glitch. This was with Netscape. With IE, I would not have been so lucky. IE has a lot of good points and is the most used browser. I develop my web pages using Netscape, but wouldn't publish any of them if I didn't first test them with IE. I run a monitor on my web site and IE has a 80 percent share of all browsers, but it is also the most targeted. Netscape is only running at 10-12 percent share, with all the rest filling in the last 8 percent. Netscape is also free. -- Martin E. Meserve - K7MEM http://www.k7mem.com |

Unfortunately, some web sites almost demand IE. The attitude is that since 99% of the users are using IE, that's the thing to code for. (I know this because I've had this discussion with my son, who is the IT guru for a nationwide corporation) This will change! Where I work, we have been told to abandon Internet Exploder. I already had years ago as part of UALMPAP (usa as little Microsoft product as possible) Between Students and Employees, that is probably only about 100,000 people. Since it is happening elsewhere too, it *will make at least some dent. I have IRA's at both Schwab and Vanguard. Some of their "features" simply will not work in anything but IE. Threats to move my money to the other guy if they don't fix this fall on deaf ears. Of course, you only threatened. If you actually moved the money, and gave them that as a reason, they might start to pay attention Same with my credit union. For example the login page "moves" three times while loading in Firefox. If I start typing my login info too soon, the boxes move and login fails. Tech support couldn't care less. As long as you still use them, they won't care. But these are the same guys who, although 80% of the users have a dial-up connection, assume that everyone has a personal T1 line to their server and can download their bloated pages instantly. A few years ago, I started seeing a lot of websites that had incredibly superflous Junk on their intro pages. An example is once I needed a ne pair of skates, and I needed them quick. I wnet to the makers web pages, and the first thing it tells me is that I need to download a plug-in in order to see their site. So I download it. Then it tells me I have to restart my computer, which is a little bit of a pain. Then it bombs my computer, then after rebooting and waiting for scandisk to check and repair it, I finally get to the site again, I get to see the critical software advance that I couldn't access their site without. It was a freakin' movie of a goalie sliding across the ice! I called them and told them that I wasn't going to buy any more of their skates and told them why. 400 bucks lost for them, actually more like 800 bucks, since I was often buying skates for my kid at that time. BTW, they ended up changing the site eventually. - Mike KB3EIA - |

Art, There was nothing wrong with your posting. It's just in the wrong newsgroup. I don't know how to make any more simple. All the best, and good luck with your "cumputor", Dave Well, Gee, Dave! I don't see you telling the "FS 8 pill linear", the "I PASS MY TEST ALSO THE EASY WAY", the "Strange question about SWR on HV lines" posters that *they* are off topic. So here you have a regular poster making a post, and another (several) answering him with helpful non-trolling, non confrontational advice, and this is a big problem for you? - Mike KB3EIA - |

I regular poster asks a question in a newsgroup where a) he is known and b) he knows the other regular poster -- kinda helpful in judging answers. I suppose you COULD have posted it in alt.cookies.yum.yum.yum but I see no problem posting it here. BTW, Firefox is great. grin Paul AB0SI |
