Don't know what I did -- after working for 4 days, with no problems -- but the objects in the Library
Browser are now only in standard display.
Went to Preferences already, tried to Rest Options. no change.
Pressing either Standard display or Vector display, there is no difference- I only get the B& W outline drawings.
All the textures and colors are visible, but display differently now.
Any ideas how to fix this without resorting to re-installing?
Thanks
