Hi Anton
Why not try writing a little function in the .dll that tells you whether
or not the form is visible? The following is an excerpt from the Delphi
docs - for the Visible property of a form:
Use Visible to determine whether the form is visible.
If Visible is True, the form is visible - unless it is completely
obscured by other forms. If Visible is False, the form is not visible.
The Show and ShowModal methods set Visible to True and bring the form to
the front of all open windows.
Regards
James
