Recently upgraded to 2014 with Sp.1 (Build 222, Release 2014 SP1 - Date Tue 09/17/2013)
I'm experiencing unstability (frequent crashes) and graphic errors with Express mode on.
With the Express mode off the crash frequence goes down and no detectable graphic errors.
Very difficult to report properly ... most recently it occured when doing a component replace
on a sub assembly with a constrain error.
Have turned off the Express mode as default. It's a useless feature
The little time it's saving is lost many times in crash lost work / restart and redo.
Just my view!
Did you send the CERs after the crashes? If yes, can you tell me you mail address for the CERs? I can take a look at your CERs and may can give you more information.
