On some Win9x systems (e.g., Windows98, WindowsMe, but not all systems
exhibit this behavior consistently), Font2DTest in the demo/jfc/Font2DTest
directory causes the system to hang.

To reproduce:
- run Font2DTest
- click on one of the characters and drag it around the screen.
There is usually some problem with regions not being updated
properly. But the larger problem is that after a couple of updates
the whole window systems freezes.

You can get things working normally again by doing a ctrl-alt-delete,
waiting for the dialog box, and killing the app in question. Note that
now DirectDraw is hosed and you will have to manually reset it by
switching display depths (or rebooting).
