Applications using fullscreen mode and doing display mode changing are likely
to run into a bug that was caused in a recent putback. In particular, apps that are using BufferStrategy will be unable to create buffers in the new display mode and will thus be unable to run (they will probably show a blank screen).

To reproduce:
- using a build that has the bug (currently only in the 2D workspace as of 7/18/03), run MultiBufferDuke (test/java/awt/FullScreen/MultiBufferDuke)
- Choose a display mode that is different than the current one
- Click Enter
- Note that the display mode changes, but that nothing ever shows up
- You might as well quit the app now because hnothing will ever appear
