Fixing the heigth of a pop-up form

Since many years I "fight" with pop-up forms, as in endless view I cannot figure out HOW to fix the heigth.



Some forms keep a height which was set by the System and it is suitable others have the full hight of the Screen and I cannot find any Setting which can influence them.



Please let me know how to define or to fix the heigth.



It only works when I set the border to "changeable", but not when I want to fix a heigth by Setting the border to "Dialog"



Thanks a lot!

Michael
