I havent't programmed in windows but i've done a quite a bit of 
programming and reading up
on PM and will say the following things
1) OS/2 PM does premptive scheduling
2) Debugging a PM applicationb is quite painful because since a whole 
lot of messages
are kept in a system wide queue wand the fetching of the messages is serialised. SO if any of 
application for whihc the message is intended is not able to do so, it will
choke up the whole OS/2 machine ?? Yum. THings like exchanging window focus and
retreiving timer messages should be taken care of immediately for the 
same reason as above.
3) Having a dual display woulld help in running the debugger in a separate window
however that wouldnot alleviate the message queue problem.

Otherwise i should say that the PM is a pleasure to work with !!
