Could have sworn there was another thread to this effect, but it's worth repeating.
Many of us are using Chrome to play Glitch, I thought I'd put this in the General Forums. The problems you're experiencing might NOT be a bug... rather a failing of Chrome itself.
In early March, Google rolled out Chrome 10. Problem is, the new version has issues running Flash. Without getting too technical, Flash often crashes at weird times, especially if you are running more than one page with Flash at a time.
So if you find you're experiencing more crash problems when playing Glitch, the problem might not be Glitch at all. It's been a month, and the problem persists. It looks like a big mess that's going to take them a while to sort out.
