Hello.
Why do I keep getting the white graph in my updated Mac OS X 10.7.5's dock for VMware Fusion as shown in my http://i.imgur.com/U4SE6yB.png screen shot/capture? Every time that happens, my VM and host Mac Mini (mid-2012) get very slow (sometimes non-responsive even with a spinning colorful pinwheel). It's annoying. Is it because I just made a snapshot? If so, then it would have been nice if it just snapshot fully first. 
Thank you in advance.
