very odd with the hibernate issue, so if you disable hibernate will the computer then shutdown in 15min?
Not a solution to the problem, but more of a temp work around, you could have a script that will click your mouse for you so it stops the shutdown so u dont have to manually do it.
Such a script is attatched to this post.
Stick it in your startup folder and it will run and wait for 5min then simulate a right click then exit.
If chose the right click since RR will ignore it. This should tide u over till u figure out the real issue.
oh and if you want logarithmic audio i believe winamp can do this. It will only work in winamp though.
