This time it's scaling. I have an activex control that takes up the entire available space on a tab.
The first time it opens, then it scales fine when I re-size the application.
HOWEVER if i close the tab view, and re-open it, the Min Size is reset to the size it was when it was closed,

[FIXED]

Code:
 
      Procedure Close_Panel         Set Size to 149 305
        Set piMinSize to 117 240
        Set GuiSize     to 149 305
        Send Adjust_Logicals
        Forward Send Close_Panel 
     End_Procedure
I'm not exactly sure which lines here actually fix it. I stopped testing when I got it working.
