Does anyone have issues using the ""Purge"" command in AutoCAD 2010 or 2012. I have tried the same with 2015. The interface is too slow to pan easily. However in all versions from 2009-2012 , When I use the purge the system crashes into blue screen. My system is a Dell XPS L502x with 8 GB RAM, and 2.2 Ghz i7 processor. Nvidia GTX570M. The graphics driver is updated, but still problem persists.
