Is that the only problem with OpenDOS? I guess not. For example, my program 
(doesn't use Allegro) works perfect under MSDOS 6, Win 3.1 and Win95 but 
doesn't get hardware interrupts in OpenDOS, perhaps is a configuration problem, 
but the users doesn't know how to configure well your OSs. I think that OpenDOS 
must be fixed in A LOT of things, Novell did a disaster with the good code of 
DRDOS 6 and now Caldera must fix it.
