[Cooker] install - beware mouse clicks

[Borsenkow Andrej]

I was in individual package selection (list view) and clicked two times
too fast. It resulted in X server ignoring any mouse click (I could
still press F1 :-) but could not go back) and after I switched to tty2 I
saw nice kernel oops and that was all. I have Logitech three-button
mouse. Sorry, no more detailed info as system died at this moment :-(
