FR Report Designer - no network drives shown in the File>>Open area

Hi all,

Strange FR behavior - when opening the FR Report Designer then going to the File>>Open area to select a report to modify, the only contents are the C drive of the workstation.  If we close out of FR and launch Excel from the desktop I can see all the network drives just fine.  Any ideas on this one??

workstation environment:  Windows 8 with Excel 2013 32 bit.  Sage 300 version 5.6 with PU2

Thanks for any help!
