Comment 3 for bug 153518

Yes, I have faced this problem too. 'Disable Sticky Keys if two keys are pressed together' is disabled on my Ubuntu 7.10 system running GNOME; yet if after starting up for the first time I leave the system alone, and don't touch any keys for about two minutes, a pop up comes up and asks me whether I want to deactivate sticky keys.

This ONLY occurs after rebooting - and not if you leave the system idle any point in time after that. It can be very irritating indeed. I may leave my system to startup, and when I come back after some time there's this popup.
