Thanks. I created a button, added and case and I pasted it in. It causes very strange behavior. All of the LV windows minimize but they loose their graphics & preview thumbnails on the taskbar. Even after restoring various LV VI windows, they are not redraw correctly. Only after I individually minimize and restore them do they "paint" correctly. I wonder if there is a 64 bit version of user32.dll that might not cause these issues.
