I just reinstalled Grokster, the program that loaded in Gator in the first place, and allowed it to reinstall Gator to its full capacity.
My browser still crashes if more than one window of IE is open. So it's got to be the new version of IE.
If I could convince people (including myself) not to have new browser windows open from their sites, then maybe I'd be okay (except for the few pop-ups which still seem to escape the pop-up killer program I installed--hey, it's keeping out quite a few of them, at least!).
