I get that on Safari tabs quite often. I use the keyboard for windows but I imagine it would happen there too.
why do programs stay open? i use the red x to shut them down but when trying to install another program i get told they are still open and have to force shutdown.
also, when i try to update leopard and itunes i get an error 'not enough user priviledges' however when i check user settings i am listed as an admin.
If you want to close the app fully then press CMD + Q. (Apple + Q)
