I found the cause of the problem.Originally Posted by Howard Kaikow
The Initialize event of the Userform includes the following statement:
Me.Height = 335
Commenting out that statement allows the Designer to display full size (not what I want).
Well, I've already converted the other 13 Designers to VB Forms, so I will soon tackle this last one, by far the most complex, as it is multipage. I'll first check whether SSTab control will do the deed.
