I use SP1, and this happened before I upgraded, too. Stardock gives great support for GC2, but for this, it's horrible. I've had this problem for about a month now, and the only "help" I've gotten was a suggestion to use the stable version. That would be great if THAT didn't crash too. You guys keep asking about what your doing at the time, which doesn't help much, cause with *ME* atleast, I get it no matter WHAT I do, run, ect. The problem is WB making Explorer crash. I can get it by looking at a picture, or talking to my friends on msn, or listening to music on iTunes, or typing stuff in Word. I can understand your trying to help, but your doing it backwards. You should figure out how to make WB NOT crash Explorer, instead of asking us what we do, as if we all trigger it by doing the same things. It's a great program, but the crashes make me wanna uninstall it, and forget I ever wasted my money on it. :/
