For years Autodesk Revit has had issues with the options bar growing and shrinking. Now a new undocumented feature of 2013. When you select anything in the project browser the options bar disappears completely. Of course this is at random and I haven’t been able to find a rhyme or reason for it. It will be doing it for a while and then all of the sudden just stop, come back a bit later. I had this issue in the alpha and beta but Autodesk was unable to reproduce the issue. My question is anyone else finding this issue?
