When working in ArchiCAD my desktop work environment (all my palettes, tool bars, etc.) will disappear. I keep another session of ArchiCAD open so I can switch to it and then when I switch back to the session I want to work in the work environment is restored. It will only last about an hour or two until it happens again. Is this a bug? I've been working in 16 for about three months and this has only begun happening in the last week or two. Any ideas what's wrong?
Thanks in advance.
