It seems that the newer version of SolidWorks I installed, the more glitches it has, more no responding, more crashes, more chances to make me close and reopen the file for modeling ...

What version? If newer version and using an older computer, a hardware upgrade may be necessary. When going from SW2008 - SW2009, I had a pretty profound performance difference between the two on the same computer. I upgraded hardware and everything was pretty good until upgrading from 2013 - 2014. I started noticing a performance difference again. Before I install 2015, I am going to upgrade my computer again.
