Hiya Folks… I got an interesting bit of information from someone on the Internet (I posted the Calc & UAE problem on USENET). He was having the same problems with UAEs after returning from a DOS shell, when he had his math-coproc active. He fixed it by saving the math-coproc state before shelling, and restoring it after returning. His theory? Windows isn't properly saving the math-coproc state when shelling to DOS. I asked him to send me the code for saving/restoring the math-coproc and as soon as I get it, I'll email it to those who've been affected to see if it helps anything. Let's hope so! – Ted There are 3 Replies.

Thanks for your efforts. I'll be looking forward to getting the code!

Hi Ted, You are right about the stack getting messed up. If you could send me the code also, I would appreciate it. Thanks, Don
