Reproduce this on Win2000 w/ 2+ video cards using the attached ScreenTest. Run the test as an applet with -Xnosecurity.

To reproduce:
-set the primary monitor to 16-bit color, and the secondary monitor to 256 color
-run the test
-drag a window from the 256-color monitor onto the 16-bit monitor. It may require some dragging to induce repainting, but eventually the thing will crash.
