I just have to say that this change in 2011 has caused us some major headaches in our small 4-station installation.  Our standard mode of operation has been to take parts from toolbox, rename them and put them in our project folder so they read correctly in the automated BOM.  The new default settings have automatically renamed and re-pathed every single hardware item in any assembly that is opened and saved.  Not good.  Anybody know of a good way to get hardware items renamed back to what they used to be named in assy's where this has ocurred without having to go through every toolbox part in the assy and manually rename it?
