It appears that non IE browsers (Mozilla, Opera, etc.) have trouble with some Internet sites. Has anyone developed a fix for these anomalies or an linux based IE clone?

You can change your browser identity quite easily in some linux browsers, eg bring up konqueror (KDE's default browser), settings > configure konqueror > browser identification > new > enter a domain (eg microsoft.com) and an identity from the drop down list.

I don't have any trouble using mozilla, and so there is no need to use opera (its not "free") and so I haven't tried it. Tell me what problem you're having with Mozilla. Its the best browser out there. Its the "standard". IE comes nowhere close. Even magazines like PC World have named mozilla the best browser of 2003. Look at some of the cool features: Skins Tabbed windows Popup block Smooth scrolling

But if you really have to use IE (WHY!!!), then you can get CrossOver Office from www.codeweavers.com and run IE under it... taurus

If you're having problems with fonts (ugly fonts) then download the latest mozilla (compiled with Xft support) from: http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.5/contrib/mozilla-1.5-xft-optimizedi686-pc-linux-installer.tar.gz Use this and you'll know what I mean by "Mozilla is the best browser".

I must agree with Audiophile. I've just downloaded and installed Mozilla 1.5 and it's pretty good. I usually use galeon (which is based on the gecko engine too) but might make the switch and see how I get on.

You have it backwards. It's not that non-IE browsers have trouble with sites, it's that some sites have trouble with non-IE browsers. This is only the case where the "designers" used Frontpage to design their site, and/or they didn't test their site properly. Frontpage makes code that is not W3C compliant. W3C sets a standard for HTML code that if followed, will ensure that a site performs the same no matter which browser is used. Microsoft does this on purpose, and then tweaks IE so that it can display the proprietary or uncompliant code generated by Frontpage. Of course the other browser development groups are not privy to what this code is, and MS intends to keep it that way. They very much encourage the idea that the other browsers are somehow substandard because it won't display the broken code their software generates. Do you see how this ties in with their business plan? Go ahead and use Mozilla or Konqueror. If you come up on a site that wasn't designed properly, fire off an email to webmaster@sitename.com telling him/her about their screw-up. I design sites, and I when I test, I use several different browsers at several different screen resolutions. It's half the job. It really riles me that some people take shortcuts and make these crappy sites that don't work. Their customers should sue them.
