We have just upgraded to SunOS 4.0.3 on our 3/260 and 3/60 machines, and have found what appears to be a single bug with various manifestations. A specific description of these manifestations follows, but it's a bit involved. Please reply if you know of ANY bugs related to color segments in SunView, introduced in 4.0.3. For the really keen, the detailed description follows: When you run SunView and bring up a bunch of tools, each of which wants a different combination of foreground and background colors, one of them (always the same one, perhaps the third or fourth to be run I'm not sure) always pops up black & white instead of with the requested colors. You can run the command to create the tool again, without deleting the first one, and you'll get the right colors on the new incarnation of the tool. (Sometimes I think you have to try several times.) Another manifestation occurs when you have run SunView and invoked any number of tools, but just black and white ones. If you then invoke a tool which wants to be black & white but with a purple-filled canvas (e.g. TAAC-1 applications), the black parts of ALL the previously-invoked tools (both window borders and text) simultaneously go purple. If you then run the TAAC-1 video editor (a tool with a slider to interactively adjust the color of the purple canvas in the TAAC tool), and fiddle with the slider, all the stuff which went purple simultaneously changes color. We didn't have such problems until upgrading to 4.0.3. My guess is that something has been changed in SunView's handling of color table segments, such that now, it's possible for several tools to share a segment, AND that there is some bug which sometimes (perhaps by returning a bad pointer) causes several tools to share a segment even when they're not really supposed to.
