Enlarging Adobe ActiveX control

[G_Loc]

I sucessfully implemented the Adobe ActiveX control (AcroPDF.dll I believe) onto a form so PDF documents could be previewed. The only problem is that the ActiveX control stays small, no matter how much I enlarge it in design view. The ONLY thing that will make it expand is if, with the form open, I manually type in a new width and height. Of course when I close and reopen the form, I have to manually edit the size again.

I've tried a whole bunch of methods that are supposed to change the size but none of them seem to work.

Has anyone messed with this control before and experienced this issue?
