Either method, Tim, is going to test for a previous instance. One word of caution about using Is_Run32() to test for a previous instance. I haven't checked this out, but there's a chance (if my recollection of how the Z-order in Windows works is correct, a good one) of getting back the window handle for the application that's doing the testing. To circumvent that. Set the .Caption to an empty string prior to calling the function, then restore it after you've determined that the program isn't running.
