I am testing the program using the VB.Net Twain Sample application.
After a scanning, the program shows a Demo Mode warning.
When this message box is closed, a black rectangle remains on the screen where the box was positioned.
This happens with any message boxes that overlap the viewer (a blank rectangle remais on the screen).
