All signals on the track monitor show up grey

[frliss]

Hi all,

I was just setting up some very simple activities on the Powder River Basin route when suddenly all signals on the track monitor showed up as grey. I looked at some other routes and the signals are grey as well. This happened several years ago and I was able to fix the problem, however I cannot remember what I did to fix it. (At my age I would be hard pressed to remember what I ate for breakfast.) I am using OR New Year MG. Can anyone help me out?

Thanks,
Fred
