Just upgraded to AS1150 this morning. The problem that I'm encountering is if I start AS with a DL from AP then click on the NF tab of AS, AS hangs up. I get the little blue circle, and am unable to scroll through the selections on NF or change back to AP tap. That is when I get the 'not responding' notice. Sometimes, if I'm patient enough, it might eventually unhang and start working again on its own. It has happened on both the 32 and 64 bit versions. This log is from the 64 bit that eventually started to function again after being left alone for awhile.
