This happens with most games I know of.  It is not always desireable
to chain keyboard interrupts - you may find keyboard buffers filling
up, tsr popups occuring, macro keys being fired.  Those sorts of
problems.

I wrote a screen blanker which had this problem.  I cured it by making
it test that it was still on the interrupt chain (by firing off a
dummy interrupt) before blanking the screen.

If there is a known workaround then why not use it?  If enough people
do complain, it probably will be fixed.
