many times ,when I try some coded, if it meets errors, or it really needs more time to process, then my computer will be somethink like locked!
I know to set memory and time constrain in evaluate expressions, but how about in the whole notebook, If the evaluation of the whole notebook meet a error or exceed the set time, it'll broken automatically, for when it happened, ALT+. to abort is useless.
I can only long-press the power button to shut down my computer when that happened.
How about this problem in mathematica 8
