I cannot pin-point if this was after I flashed up to Diablo, as originally I thought it was a Canola issue - but I realize my Power,Home, Switcher and Screen Lock keys no longer function. Well the power button powers on/off but I have to hold it for a long time, and it's essentially a "hard reset" - no options to lock the screen or gracefully shutdown...

Touch Screen and keyboard based hard-keys seem fine. Any ideas or remedies anyone can point me to, would be greatly appreciated.

Also if this is somehow PEBKAC (not unknown with me) and I installed something quirky - what program would have disabled these keys?

All Ideas Welcome.
