I have two jobs (one part time), where I have SolidWorks 2015 sp3 on two different systems. One is a laptop(HP Zbook) and one is a workstation(Dell T3160). I freeze up probably 5 times a day on each one. Where the software becomes unresponsive and the window pops up for me to "wait or shut down." It happens when I drag and drop a new part, edit a  parts dimension in an assembly, when I unsuppress, hide - unhide component. I am getting very frustrated, and so far my tech support has no answer with two separate RX captures that report no hardware or software issues. Any one else having these problems?
