IE5 to 5.5 First let me preface this post by saying that I'm not talking about my computer and the person I'm trying to help does not want to upgrade their operating system. I'm working on a Dell dimension about five years old that came installed with Windows 98 and Internet Explorer 5. He's having a little problem that I think may be with Internet Explorer. The problem is that on a couple of sites the computer temporarily freezes for about 30 seconds and then is fine. This does not happen on all sites. One example is on Yahoo they have a search window and when he tries to search it hesitates for about 30 seconds and then goes to the search engine page. My question is: can I downloaded Internet Explorer 5.5 service pack and install it on top of his Internet Explorer 5? Or do I have to have Internet Explorer 5.5 before installing the 5.5 service pack?
