Why when I quit and open A+ 2.0 it needs to scan the whole library again and again and it takes few minutes where the CPU is busted on over 100%? It is quite annoying, so I think scanning process need a real treatment and improvements.

 

BTW, I have noticed on my DAC that after stoping playing in the A+, after few minutes time to time the LED on my DAC indicating the LOCK starts quickly blinking and I can hear cracking in my speakers. Then it stops and happening again. When I resume playing it plays fine. It is like loosing the LOCK time to time when idle or something. I have never seen this on previous A+. I am using toslink and 10.7.5 Mac OSX and yes, I've checked all my cabling as well. Any idea?
