"The attempt to power off PC failed"
I've just upgraded to the latest RR, and now cannot shut down the computer using the power button. Nothing happens at all! When debug mode is enabled, nothing gets written into debug.txt at that moment. I only could find this message in the system events log: "The attempt to power off PC failed".
This happens almost every time when RR is set to run as a shell instead of the Explorer.exe. Very rarely it does shut down, but I couldn't find the exact conditions, which make it work.
If I return shell back to the Explorer.exe and start RR just via a shortcut in Startup menu, the power button seems to work, though I believe it still failed even in this mode at least once.
It worked perfectly with the older version of RR (I believe it was 2009-11-30).
Is there some setting for the new version of RR, which could prevent Windows shutdown?
I'm using Windows XP Pro SP3.
