As soon as I press Ctrl, poof goes whatever I'm doing. It's only happening with 13.04. I had Lubuntu 13.04 before, Ubuntu 12.04 before that, and Windows XP came with the original install in this HP Mini 100.
I did not give the Ctrl key any special privileges and tried to see if it had any shortcut assigned but I have found nothing. The main problem is I can not use any shortcut because the window will close.
Any help to change that behaviour before I decide to downgrade to 12.04?
