I am currently using SW 2011 sp4.0 64 bit. my computer is intel Xeon 5140 @2.33 GHz with 8 GB of ram. I start out the morning by opening PDM enterprise, then SW. The file I am working with is almost 47,000 KB. Computer is running realy slow and I continually get a message which states "SolidWorks has detected that your system resources are running low. It is recommended that you close some applications to free additional resources." I have no other applications open. is this a ploblem with 2011?
