Well, if the max-installed-colormaps value for the screen is relatively low (which it will be on most hardware - typically 1), you can create that many colormaps, install them all, and then deinstall them. (I'm not sure how you keep the window manager out of your hair while you do this; perhaps this must be added to the window manager.) Speaking of this, is there any way of making all windows refresh themselves? That sounds like a stupid question - just use xrefresh, right? Sorry, not quite good enough. I have sometimes observed the R4 server keeping backing-store when it hasn't been asked to, and while there's nothing wrong with that per se, it uses the frame buffer memory to do so, which *is* wrong, because it means that a program such as screenload will corrupt the backing-store as well as the current window contents. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
