everett freezes loading dorchester project?

Staring a a while screen that flickers every 30 seconds or so ... windows tells me Sonar is "not responding". 
 
Trying to load a current project, saved in Dorchester, nothing special about it that I know, except fairly heavy load of VST instruments.   
 
Any ideas?   Memory stuff different in the new build?    
 The 'performance' module has not updated, during all this flickering, though most of the project looks open (until I try to do something).    According to windows task manager, sonar is using 24 GB memory, a lot, but less than half of what's available.    CPU at about 10%.      Been watching it flicker for about 5 minutes so far ...

As I keep watching this thing flicker ... feels like an hour now ... I get the strong impression that it is trying to replay the last few hours of work, before I saved the project in Dorchester and loaded in Everett.   Is that possible?  Something to do with the undo stack?    Still seeing two independed now times, and they are still changing, every 15-30 seconds.   This is from the initial load of the project, I have not done anything at all (like push play, or change a value somewhere).
 

Another idea:  could they have put in something that is going to want to go on the internet?   Secretly?   And doesn't stop trying?    I always turn off the network adapter except for things like downloading updates.
 

Hi. To your last question. I have used SONAR both plugged and unplugged from internet, without any difference.
Try to open the project in safe mode ( Press Shift while opening), to check if there is any problems with a plugin(s).
Best of luck.
