Coz you on windows.
Different OS not everytime allow resize or move with top frame border. So your workaround dont help here.
do you have this kind of problem?
Sure, if i ask about this problem.
It's strange that your're not able to resize the internal frame. Resizable is one of the attribute set by java code and not by the operative system.
If you are not able to resize the frame, and you are not able to set a higher resolution i don't think it exists a solution
