1. We have on rare occassion seen the window manager appear to lock up in that there is no response to mouse clicks. Hitting the Escape key usually restores normal function. This problem seems to occur only when we were switching between applications on the screen.
2. Occassionally a warning may be seen written to standard out:
Warning: Cannot allocate colormap entry for "#608189"
Popups and pulldowns are usually written to the overlay planes. There are only 15 colors available in four overlay planes. The message is written when the motif interface is unable to allocate an additional color and is of no consequence.
