Mac Shut-down Bug

[Michael Anderson]

Hey, has anyone had any problems with Lyx freezing up on shut down?   
I've been having trouble with this for a little while.  I'm using Lyx  
1.5.1, on an intel based mac.  This makes me a little nervous as when  
I check my system monitor it shows that the cpu is getting pretty  
toasty and LyX is using about 50-60% of the cpu.  Anybody have any  
thoughts?
