Steps to Reproduce Behavior

1. Start a new project in the 16-bit edition of Visual Basic version 4.0 under Windows NT. On the File menu, click New Project. Form1 is created by default.



2. Place a Command Button (Command1) on Form1.



3. Set the DragMode property for Command1 to "1-Automatic."



4. Set the DragIcon property for Command1 to an icon.



5. On the Run menu, click Start.
