I installed IE7 when it was new, and I've kept up with all the patches through Microsoft Update. I have XP home edition with a souped up NVidia graphics card, and my desktop system is over 2 years old so it's not the very latest.
IE 7 freezes quite often when I'm on a web site. It happens on a lot of web sites, such as www.NFL.com and the flash based courses at epgy.stanford.edu. But it even happens on plain text web sites like www.zoltan.org.
It doesn't seem to be related to a specific reproducible action or a common feature of the web sites. It just seems to freeze and become unresponsive. I have to terminate IE7 and it works OK when I restart it -- at least for a while.
I have laptops with IE7 and they don't have the same problem. Any thoughts
