But *what kind* of idle calls?
This is the vital info. If you
can't find the answer, then the
problem can't be fixed:)
int 0x28 is the real idle call,
but since dosemu catches that,
I suspect clipper does something
else.

Yes, and the system must not be
crawled now at least. At least in
a theory:)

That might be not the case either.
FreeDOS can just call int16 to do
a blocking wait for a keypress, and
that will do the trick.
You have to find out what exactly
the clipper does however.
