I have a large form that I use as a pop-up.  I would like to control the size
of the form when it pops-up.

My current settings are:
Auto-Resize: Yes
Fit to Screen: Yes
Border Style: Sizable

If I take off Auto-Resize it fixes the height, but extends the width of my
form by aprox 2 inches.   The fit to screen doesn't appear to change anything.

I would really just like to set the width and height of the form on the
pop-up and let the user use the vertical scroll bar.

How do I accomplish this?  Thanks in advance!
