Actually I run Paradox/DOSV4.5 under win95 and if you set things up right
it can run protected dos space and the cooperative multitasking is only
within that virtual dos window. It's a bigger probem that it tried to
to the printer directly and Windows blocks on that if the setup is not
exactly right.

NT4 also has this and it works well. BUT, you have to watch as some dos
programs may try to share a file and you can get file locking problems.

Keep the education going.

Its clear that NTs dos support is based on OS/2s.

Just for curiousity I've got a OS/2 Warp V3 kit including the bonus pack.

What would it take to get networking going (TCP/IP prefered)?

Also what later versions can be purchased and approximate cost?
