I asked and he said that he had nonoe, but he will look trough the code

I havn't realy noticed any problems before. Most program works as they
should. I guess these problems would only occoure if you use XBIOS

Hmm.... that's an idea. ;-)

But again, those problems will only occoure if you use XBIOS calls
right?
