I just completed the upgrade of everything, and after a reboot, I have got some broken software. I am getting error messages from the NCAR command language that "Specified Workstation is NOT Open. In addition, a system call to opngks_() could not open "wrf_mass_plots.ncgm" which is the file it needs to read to produce the metafile. What changed that would cause software to think the workstation is not open? Next question.. is it possible to undo the upgrade, or would I be better off doing a clean install of system files should this breakage not be repairable with simplicity?
