We are using a home-made PDM system (based on MSAccess and SQL) and have since switching to Win7 encountered a problem. When opening af file from within SW, the path uses the mapped drive letter for the location of the file e.g. T:\\SW-drawings\\..

Opening the same file by searching with windows explorer and double clicking the file, the path is in UNC format, e.g. \\\\server-name\\foldername\\SW-drawings\\..

This causes our PDM to loose the connection to the file in question, and changes in the PDM data is not reflected in the drawing.

After opening a file in these two different ways, the recently opened file list in SW has two instances of the same file (see screendump):

Is there any setting that would consolidate these two instances into one in SW, or do we have to change our PDM-system?
