Hi Gabriels, the Nemesys guide is the only one I seen on tweaking that actually says to turn it OFF.
I did this, and when my computer rebooted, it said it coudlnt load certain system files. The hard drive would chugg away like mad for about 20 minutes and I was watching a blank blue desktop, the icons hadn\'t even loaded in. I tried booting in safe mode, all sorts of things. In the end, i had to do a full re-install.
I would have to say that this tweak in particular has burned me the worst.
