Has anyone else seen this happen? We have been using a (DFS) file structure for 2 or more years and both 2009 & 2010 Revit Structure have been able to open folders under the DFS system, until we just installed 2011 Revit Structure side by side the other installations. Now 2011 can open folders, but 2009 & 2010 can not (even if you highlight the folder then click "open", they just sit there.)
I do not see why installing 2011 would cause both of these to stop reading a DFS file structure.
