Have tested this several times. Most times, it crashes out with no error report window. I do sometimes get to the point where I can get new document window to appear and create a new document and haven't tested much beyond this.
Seems to be exacerbated if I don't wait long enough after it loads to start accessing the interface. Not sure exactly what is producing the problem. Messing with the swatches panel could be a link as well (with no document loaded).
I also reported an apparent bug related to swatch panel being docked/undocked that locked the interface temporarily in the last version.
