Hi,
you might have stated your keyboard driver first ...
but as you later state that the problem occurs with MKEYB as well,
here's my educated guess what happens:
the UP, DOWN, LEFT, RIGHT keys in the cursor block are similar to the
UP, DOWN, LEFT, RIGHT in the numeric key pad as they send
Hi Tom,
something in your machines blocks interrupts for too long, and
keys get lost - most likely some TSR or driver, ...
In addition to reducing processor speed with FDAPM, I was using
Japheth's HDPMI16.EXE, as well as DPAKBD.COM to provide processor
