Thanks. Frustratingly enough, Yahoo worked and so did links off of that. It's one of those things that bugs you but when you try to show someone else...
Btw, this can also happen if I select one of my Favourites from the menu. Just never seems to happen when I click an internal link. So like I can read a linked thread on ATOT, but if I go to pics.bbzzdd.com then I normally have to refresh every time.
I've been using the latest Adaware with updates to scan for spyware, every week or so. The problem's been going on for about a month now...
