This has been an unexpected development and I can think of no reason that it has happened as everything I've done has been as I've always done it. No weird installs or anything unusual.
I checked that the video drivers were up to date and even did an uninstall/reinstall of them, to no avail.
Has anyone ever seen this before? Images of the problem are attached.
Nvidia Quadro NVS 55/280
Please let me know if any other information might be needed to solve this one. I'm getting ready to just start over and wipe/reinstall everything.
