In my recent documents list under the big A all but 2 of the files listed are sheet sets. The problem is these sheets sets were created about 5 years ago and they haven't been opened in over 3 years (mostly likely in ACAD 2010, not one of them has been opened in 2013). I have opened and saved more than enough drawings without opening a sheet set to a point that the list should be filled with nothing but DWGs. This didn't occur in 2102, the list in 2012 is filled with nothing but DWGs.
Does anyone else have this "problem"? Have you been able to "fix" it?
