Well, all VB-based programs are strange as the window that is displayed in the taskbar is not the window that is displayed on the screen.

Run the registry editor, go to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\R2d2KernelAuthority\Parameters key, edit the MultiWindowsPrograms value and add a new line *\eVb3.exe (if eVb3.exe is the name of your executable).

Let me know if you still have problems.
