>From: Unidata Support <address@hidden> >Organization: TASC >Keywords: 200101031328.f03DSuo12756 McIDAS-X X display visual CIRCLE Randy, I got our aged DEC OSF/1 machine up and built the latest incarnation of my McIDAS distribution on it. I was able to get some time to crank up McIDAS from the system console (our office is in complete shambles while trying to move back in), but I could not reproduce a red tinted McIDAS image window, nor could I reporduce a red flash from the console when logging off. X on our DEC Alpha is running in 8-bit mode (the video card does not support any more), so I can not run it in a mode that simulates your build machine. Since these machines are in a secure environment, I can't logon to either of them (true?). As you might guess, this will _really_ make troubleshooting the problem difficult. My only thought is to touch base with the other two sites I have that use OSF/1 and see if they have any ideas and/or have seem anything similar to what you are experiencing. It might be helpful in the long run to get the specifics from you about what video cards you are using in your machines. I will check with my system administrator to see if he can find out if there are needed system patches for your revision of the OS: uname -a = OSF1 nimbus V4.0 1229 alpha Tom
