Strange problem here that cropped up yesterday. Sometimes when I hit command-W the Mac registers it as having been hit twice and closes two windows instead of just the one in the foreground, which can really be a hassle in web browsers and the likes.
Now I'm sure everyone is thinking that it's because I'm holding down the W key too long, but trust me, I'm not.
This happens in applications that don't even register a held-down command key as more than one action (closing the foreground window in this case). It's also sporadic.
I'm running a standard System Folder, nothing out of the norm. I haven't yet ran a virus checker but I doubt I have one. Could be a problematic keyboard (FireWire PowerBook) Can anyone offer any insight?
