Dragging window-caption outside viewable area prevents user to access buttons

What steps will reproduce the problem?
1. Open a window
2. Drag the window to the top so that the caption is out of the viewable area

What is the expected output? What do you see instead?
You cannot click on the buttons anymore or re-drag the window.
In an OS like WXP you cannot move the mouse outside of the viewable area,
thus preventing the dragging of the caption out of the screen.

What version of the product are you using? On what operating system?
0.5 on Windows XP (GWT 1.3.3)

Please provide any additional information below.
Hotfix through events:
   public void frameMoved(GInternalFrameEvent evt) {
         GInternalFrame src = evt.getGInternalFrame();
         if (src.getTop() < 0)
             src.setTop(0);
   }
