I installed the F10 preview which i downloaded yesterday and my up arrow key doesn't work in X. When i press it it takes a screenshot. The Print key does nothing. Ctrl-Up takes a screenshot of the current window, as Ctrl-Print should. Ctrl-Print does nothing.
In the gnome keyboard shortcuts dialog, "Take a screenshot" is set to "Print". If i try and set it to the Up arrow, it gives a warning telling me the up arrow cannot be used - so, at some level, X has the key mapping right.
This problem is the same whether focus is on gnome-terminal, Firefox, the keyboard shortcuts dialog, or whatever. All other keys appear to work ok.
I'm dual booting with a F9 system and, using the same home directory (therefore the same user config files), i don't have the same problem with that.
The Up arrow key works fine in a text console.
It's been so long since i had to debug this sort of thing that i've forgotten where to start. Can anyone give me any suggestions?
