Dos applications under WIN XP

Slow DOS Applications

We are still running one DOS application, and we try to get read of IT in a near future , thats what we said every time MS releases a new OS.
We had the same problem with win95 an win2k.
But we manage to solve the problem by
Creating a shortcut to the DOS application on the desktop, and then try by trying to set various levels and types (EMS/XMS) of RAM access for the application. This solve our problem for few years, Now we got XP an we didn’t manage yet to get read of the DOS application.

We can open the application but all other windows applications just don’t load at all.

ANY Answers to this ?
