Resetting it to 16 bits helps quite a bit, but doesn't completely
alleviate the problem.
Another thing that might help my poor reflexes in catching it faster, is
if the keyboard auto-repeat could be turned way slower, or even off.
That would be a PITA, but would be better than an endless repeat at a
speed far higher than the screen can be updated.
Is there a facility to adjust that?
Thanks all.
