When ChangeWindowAttributes is directed to change the background pixel for a window, does the server attempt to free this pixel value from the color map, or to decrement the appropriate color cell's ref count? My inspection of the server code suggests that this is not the case. When xsetroot -solid is invoked repeatedly with different colors, the old color cells are indeed freed if appropriate, but that's because xsetroot itself takes these special pains. TIA for any enlightenment; apologies for my own stupidity. ==================================================================== Doug Tomm doug@jupiter.com jupiter!doug@ucbcad.berkekey.edu #include <standard_disclaimers.h> #include <cute_quotation.h>

No.

Right, because it's creating resources that need to survive the lifetime of
of the client.
