Anne, it's a desktop. I don't know what the little darling did but it fixed itself and everything's fine now. Although, it's getting harder and harder to work/play at my computer...one cat tries to take over the keyboard, one lays on top of the monitor, watching the screen upside down, and the other wants to share my chair...not beside me, not in my lap, but behind me, sharpening her claws on my backside...ya think they're trying to tell me something?!
