I run X1d (waiting for a patch for X2 before I head on over), and have never put my PC into sleep mode. It was running a bit nuts, so decided to try rather than shut er down.
All seemed well, but when I ran Sonar after awakening it, my UAD plugs wouldn't load because it said it didn't have the authorization file, Sonar would crash when opening, and Firefox wouldn't even connect to the net.
So it's likely not an X1 thing, just the way Win 7 'wakes up'. Anyone have any insight to this??
