I've just started back using BYC some over the last few weeks and I'm finding that at times input freezes with a Windows pop-up appearing telling me that a script has stopped running. Upon clicking continue the computer may be completely frozen. I'm running Win7 Pro 64-bit. I haven't had this problem prior to coming back to BYC, though certainly there could be something that coincided with my return. Maybe my system doesn't like the scripts running the ads? I've ran CCleaner, rebooted, cleared cookies, ran/run AVAST!, etc.,. Or, it could be "just one of those undocumented Windows features".
