Matt,

Another solution: trigger the pgf resize logic to fire twice and it'll compensate. I used this Form.Resize method:

with this.pgfMain
   debugout debstr( .PageHeight, .PageWidth )
   .Height = this.Height - 30
   .Width = this.Width - 30
   debugout debstr( .PageHeight, .PageWidth )

   .Height = this.Height - 30
   .Width = this.Width - 30
   debugout debstr( .PageHeight, .PageWidth )
endwith

I noticed that with just one set of code in there when the pgf needed to adjust the number of tab rows it was off, but then sizing the form a little bit got it to the correct size. So hitting it twice during the initial resize fixes the problem.

Also the .PageHeight and .PageWidth do seem to be changing for me during this sequence.
