Hi Eugene,
My welcome to PCHF, I don't believe that I've had the pleasure.
Have you completely uninstalled and reinstalled the program?
Have you tried same for the keyboard?
I would try an SFC scan, Start, Run, type in
sfc /scannow
Hit enter, you will need the OS CD in the drive for this.
Just in case one of your system files got corrupted.
Looking forward to your reply,
TTFN
LGW
