This isn't completely true. A Windows application is free to make any use of SMALL FRAME EMS (LIM 3.2), but may not invoke any of the new (4.0) functions except for (I believe) function 18, Reallocate Pages. As long as you follow these rules, you will not conflict with Windows or other applications.
