I've been running XP Pro for a week now. My first install was over Win 2000, but I encountered several problems, so I wiped the drive and started clean. That fixed all of the problems except this most irritating one: Seemingly without reason, IE will not follow some links. They can be XML links, HTML links, whatever. And it's only some links, not all. Some XML, HTML, VBscript, etc. links work just fine. And I'm not talking about links that may just be coded wrong, because there on big-name high traffic sites, and work fine with IE on Win 98 machines. When the link refuses to work, the IE window frame will flash inactive and then active again (like another window is opening and stealing focus), but then nothing happens. It's like I never clicked on anything to begin with. I'm building a website right now, so of course this is frustrating. Anybody have any clues? Thanks in advance! P.S. - I'm running behind a NAT firewall, but so are the other Win 98 machines that follow the links just fine.
