Python Addin extension stops relative paths from working

DazSalar

Hi. 

I have python code extension that runs on startup. The MXD has "store relative Paths" turned on by default. The script works well and does what it has to do. However every time the script runs it stops the ""Store relative paths" in the MXD from working and breaks the link to the local gdb. The script simply resources some of the layers in the MXD to the new SDE database. So not sure why its interfering with the "Store relative paths" for the local gdb. If i remove the extension and my code is not running then Store relative paths
