Actually, the CMU version crashed a lot on HP-UX (a variant of system V), but didn't crash at CMU because (as I understand it) they use 4.2 on their Hewlett-Packards. The crashing problems (now gone) were related to system incompatibilities. X PROBLEM? The 4 bit-plane version of HPUX pointed out a problem with X. In order to get all 4 bit-planes, I had to use (and change) colors 0 and 1, which fortunately are writable. However, if any other windows use non-writable colors (xterm for example), Magic will not run. It requires all 16 colors on a 4 bit plane machine. X should provide some facility that "hides" or iconizes other windows, saves their colors, and frees those colors. Then programs that require all the bitplanes on the monitor can run, even though other windows have allocated colors. When a color-hog program finishes, the hidden windows reappear or de-iconize. I'm sure other graphics users want to use all the bitplanes available on their monitors sometimes. Seems like X should provide some convenient way to do that. _D_a_n_ _G_r_e_e_n_i_n_g _A_R_P_A- dgreen@CS.UCLA.EDU _U_U_C_P- ..!{sdcrdcf,ihnp4,trwspp,ucbvax}!ucla-cs!dgreen
