OK I got carried away - mooo (not Mooo!) should be alerted each time the browser is resized. :)

It's not a Crash. The Browser Window is "opaque" (white screen). Also, if you have 2 windows open, the other one is still alive.

This issue is not limited to mac os x, I have experienced this on windows 7 64.

It seems that cmd+r/f5 seems to bring the page back. Odd issue.

Maybe the alert overlay is not resizing with the browser, and going over the entire browser space?
