Cathy,
Have you looked into the code in your message dialog to see what it might be doing to cause this behavior?
>The buttons have captions as well as pictures. I've also discovered that the behavior is happening on ALL buttons in the app. It's just a matter of getting our message dialog to appear first and then the buttons with pictures act squirrelly until the form is closed. I'm going to see if I can create a simple repro scenario and I'll let you know.
