Paul Herber, You are my hero. I can't tell you the hours of troubleshooting, reinstalling, and consulting with colleagues I have done to solve disappearing dialog boxes that have always worked before. I have a live session scheduled on Tuesday where I will need to work with them in Visio live, and my next step was to pay for support. I read your short sentence, tried it, and my dialog boxes were restored. Profuse thank yous.
