These days I'm trying the new version of PB on W7.
I tried to install it on your laptop and desktop in the office and seems to work well.
In my office machine I have installed of all kinds programs including avg, and PB Manager work fine.
As if I install it on a dedicated machine with clean install W7 PB appears to be unstable, sometimes does not start and I hope to force the shutdown the machine.
What can it be?
Thanks, Alberto
