I am trying to run some DOS programs from windows that need virtually all of the 640K of program space. If I remove HIMEM from the config.sys and run in real mode the program will work from windows 3.0. Is it possible to create a batch program that will remove HIMEM from memory and then run my program, and replace HIMEM afterwards? Also, when running certain CAD software (graphics intensive) I have trouble returning to windows. My guess is that some important stack information is lost, or perhaps interrupt vectors are corrupted. Any thoughts on how to fix this? Thanks in advance, Jeff Schuenke
