My intention in providing the information above was to demonstrate that the problem you are experiencing has _nothing_ to do with McIDAS-X per se. McIDAS appears to be built and installed just fine on weather, and I assume that the same thing is true on weather2 and weather3. re: > I'm still scratching my head here. > CentOS 6.8 has been frustrating, to say the least... There is something else weird happening on your machine, but I can't put my finger on what it is. I say this because I upgraded my Unidata workstation from CentOS x86_64 6.7 to 6.8, and I have absolutely no problems with X displays. I will talk to Mike Schmidt tomorrow and get back to you with whatever we figure out...
