I am using Windows XP Home with SP3. I have recently had trouble with accessing links from some websites to others, and sometimes even with getting one to download after typing the correct URL into the address bar. What generally happens is that when I click, nothing happens OR something happens, but doesn't complete. Sometimes I can achieve success by clicking the Stop button, followed by Refresh, but that doesn't always work. Sometimes, clicking the link again will do the trick, but not always. Repeatedly doing these things also sometimes works, but not always. It's a particular nuisance when the link in question is supposed to log me out of something. If it only happened occasionally, I could cope, but it's happening a lot and really slows me down.
I think it may have started to be a problem following one of the Microsoft updates (which I always install when they are offered), but I can't be sure of that. Also, it makes no difference whether I use Firefox or IE.
