Most irritating issue as of now?

[Confused]

Interesting regarding PC resources. I've never had an issue with AIR with Win7 or 8 on an old (2008) and slow first generation Asus Eee Box, but have had repeated issues with a 2-year old and by most standards powerful gaming PC running either of those OSes and optimised to remove unnecessary services etc. Always wired-throughout gigabit Ethernet in both cases

There might be something in this.  I can only really comment with respect to what the power management settings do with respect to my PC, which is a year old quad core Intel i5 machine.  As it happens, my previous (clapped out) Windows Vista PC ran AIR perfectly, zero issues.
