The awt/2D causes deny of services on win32.

When running HotJava using 1.2 beta4 build I on winnt with 8-bit color map. When I bring up another window to cover the HotJava window, the HotJava take 100% cpu time to do something I don't konw. My initial guess is when the other take the screen, it cause color map change, so the awt/2D try to response the message, and race the color map(pallete) with the front window. However, as a background window, it should not do anything in this case.
