I have a Sharp WS003SH (VGA screen) running WM5, and the proportions of the main screen (the one with all of the lessons showing, not the one with file names) won't resize properly when you go to/from landscape mode.
So, if your device was in landscape mode when you opened the file and then change back to portrait mode, the window will extend way beyond the boundaries of the screen. If you opened it in portrait mode, changing orientation will result in a window with reduced width.
Also, if you go from a disformed main screen to the Edit dialogue, it will have two sets of scroll bars (scrolling the new one will lock my WS003SH up, but then again its pretty buggy), but if you go from a normal-sized main screen to the Edit dialogue, you can change orientation and it will resize properly.
