Thanks Guys,

I got some help and found an answer. Its a game without a title bar. Has a Minimize button so people can play at work! Also has an Exit button. Program does a lot of calculating and may need to be minimized or exited during these calcs. Here's the code that works:

"Lots of Do Whiles"
"Lots of calculations"
DoEvents
If Forms.Count < 1 Then Exit Sub
"More Calcs"
"Lots of Loops"

DoEvents handles the Minimize & Exit buttons. The Exit button Unloads the form but the code will try to continue to run which results in errors. The If...Then stops the code.

Thanks for all the help,
Jon
