Thanks for your reply. No, I don't use Vista.
It all is fine after I cleared up the mess that was in the default screen.css This file also created problems with bullets.
Also, I discovered that sometimes when I create postings with bullets or tables that are done by the template in the editor, the app never returns and times out with the content lost. If I clean that up by removing some attributes that are defaulted in the editor, then it saves.
