when I open SolidWorks, it takes a big chunck of memory. that's expected. However, when I close out of a session, and bring it up again, for whatever reason, I sometimes get a message that my system resources are running very low. My IT guy comes over and looks at my tasks and says my computer shows 2 sessions of SolidWorks. So the first one did not end when I closed out, but the 2nd time I opened SolidWorks, it started a new session. I have only been getting this since usine SolidWorks 2010. It does not happen everyday, but it is regular.
