What about a resident remote control program like Teamviewer being run in the 
background.  I get all kinds off goofy keyboard stuff with that.

My WAG: Weirdness with a wireless keyboard, or perhaps an intermittent 
short in the keyboard cord.

If you want to find out what's going on, you could probably do:

foo = .T./.F.  && Whichever will be harmless later on

TRY
    foo = CHRSAW()
CATCH
    * Log foo here.
ENDTRY

IF foo = [whatever]
     * Your code here
ENDIF

I'm sure that's obvious though. :)
