MDI: When the source editor is maximized and the Tools|Options menu item is selected, the application hangs. It will no longer accept mouse input. When the mouse is over the source editor at this time, it flashes _very_ quickly between the arrow and the cursor, making it seem as though it's going into some loop switching back and forth. NetBeans must then be killed through Task Manager. Steps to reproduce: 1. put the -ui com.sun.java.swing.plaf.windows.WindowsLookAndFeel flag in ide.cfg. 2. Start NetBeans. 3. Open a source file. 4. Maximize the source editor. 5. Select the Tools|Options menu item. 6. Application hangs. It is using (effectively) all of the CPU during this time. Interestingly, this doesn't happen when the source editor is not maximized. When the source editor isn't maximized and the options windows is brought up, everything is fine. Then if you double click the source editor's title bar to maximize it, the application hangs again in the same way.
