Sometimes (steps below looks that they leads very probably into this behaviour),
maximized editor window is under output window and (of course) no scroll bars
for movig of whole editor window are not shown (they should not if it is
maximized). It is quite annoying.
1. Close editor and output windows
2. Restart IDE (this step looks to increase probability)
3. Open file in editor while output window is closed.
4. Compile so that the output window is opened (if the output window do not open
after normal compile, make some errors).
5. The editor sometimes stays on its previous size, so a part of it is under the
output window.

Tested on Solaris, Sun JDK (1.3.0_2), MDI, pilsen build [010505]. Tested with
form opened in GUI and editing mode. The workspace was GUI Editting.
