That is strange. It works for me OK on my 386/25. I start 4dos (now 3.02, but
it worked under 3.01a also) using XMS swapping. Then I can start multiple 4dos
windows under windows 3.0 with no problem. In fact, they share the same
environment space so that XMS usage less for the subsequent 4dos windows.
