OK, here's a weird one...
One of my favorite features of Vista- and even more so, Win7, is the "Sleep" function.
It's been functioning fine until a few weeks ago when I installed the first "leaked" version of Win 7 RC1.
Now, every other time I put Sprocket to sleep, the screens go dark but the PC remains powered on and I have to perform a hard shut down.
I mean "every other time" quite literally too...she'll sleep perfectly once, then the next time, not.
Hard shutdown/restart...next time, sleep fine.
Repeat, ad infinitum.
Can't imagine what might cause such odd, but perfectly regular, behaviour.
I have an official MS RC1 and am considering a reinstall to see if the weirdness continues but until then, any suggestions or theories are welcome.
