This statement may be out of place because I'm still using 2013, but I'm gonna make it anyway.  If I have SW open & I use Internet Explorer or SolidWorks Explore to open a drawing, SolidWorks opens a new session instead of opening the file in the already open session.  When this happens I get the following message: "A journal file could not be created.  Auto recover will not work.  Another session of SolidWorks may already be running on this machine."  Is this a common issue that others are experiencing?  Is there a setting that would allow the file to open in the current running session?  Or was this fixed & I need to find the time to install 2015?  Thanks.
