graphics in gray. 800XA ver 5.1 rev E
we have a problem in one Operaror Workplace in 800XA,
the graphics appears in gray. and then the system is block,
as you see in the picture,
all the services are ok,
the engineering workplace is running,
and the operator workplace is open,
but the graphics displays are grayed,
the engineering workplace work normally, but if we go to functional structure and select one graphic aspect, the enginnering workplace is blocked.
the computer is ok at domain, the 800XA system is ok,
the problem is just in this computer,
someone have any recomendation, to check

If all PG2 graphics on this node can't be shown, you should first test to purge the WPF Font cache.
I see Stefan had a valid point with .NET reinstall, but I would test this prior to Stefans recommendation.
This is a known Microsoft problem kb937135, unfortunately they have removed a support page explaining this, as this is an older operative system.
There is a simple fix:
-stop WPF cache service (Windows Presentation Foundation Font Cache 126.96.36.199 service in Administrative Tools/Services in Windows)
-delete fontcache dat file (found in C:\Windows\ServiceProfiles\LocalService\AppData\Local\FontCache188.8.131.52.dat)
-start wpf cache service
Hope this helps
