Could you be a little more specific on what you want to accomplish?
Without knowing what you want to do, it's really difficult to provide
any meaningful advice.
Concerning general behavior of JFrames vs. JInternalFrames, if you want
the new Frame to be confined inside its parent Frame, then you should
use JInternalFrame.
