- I placed a call recently on such a problem. It involved watchdog resets,
- and window underflow. This was occuring on a SS1, with Monochrome monitor.
- Sun said it was probably a bad framebuffer. I replaced it and have not seen
- the problem again. Mine would also occasionally "hang" or appear to have
- a jittery screen.
