This is true, last time I heard.  I don't know why.

I don't know.

This will be possible, via thunks.  I don't know the details.

Full-screen apps have always been discouraged by those who feel it is
time to let progress progress.  Whether or not the OS/2 folks (the Boca
Bunch) feel this way, I don't know.  I have been pushing to get Comm.
Mgr. and LAN Req. to become PM apps, but I don't know what the current
status of that is (nor could I tell you if I knew, I'm sure).

>(sob, sob...)

LPEX?  What's that?  Never heard of it...  ;)
