I'm not able to get it to recreate with those steps...
HOWEVER!!
I went in and removed the sgc-toc.css file that I had stored in the preferences folder this morning....and then it DID confirm!!
So, somewhere between creating a new sgc-toc.css file vs. using a templated one??
Is this a good summary of what we've seen reported here?
-creating a new sgc-toc.css blanks an existing stylesheet
-linking to an existing sgc-toc.css blanks the existing sgc-toc.css
-adding a template sgc-toc.css keeps everything normal
