This problem has happened to me with many different programs, simply because I am happily typing away on an instant messenger (, looking at the keyboard and not the screen I may add seeing as I am not a skilled typist,) when some program or other decides to access the internet at the most opportune moment. I inadvertantly press the return key or some other key which suggests 'No' in accessing permission and without realising it my computer decides to throw a wobbly! (Is that a word to add to your "When I say this it means...." post?)

Just a small point always check you have set zone alarm to 'allow' in all 4 boxes
