Bug ? properties panel not displaying information

Sometime in recent updates, the properties panel has inconsistently stopped displaying information. Sometimes it works, sometimes not.

Any chance this is an Appearance color thing?
If you switch back to Default colors does it seem to work agian?

Hi John - doesn’t seem to be an appearance thing, and I can’t get it to replicate again. I have been thinking it might’ve been happening when I open a non-3dm file from Explorer into a Rhino session, but multiple attempts to repeat/cause the problem haven’t been successful. I will pay attention if it does and reply back into this thread. thanks!
