Really? That's interesting.. Never does that to me.. It clones my wallpaper without a taskbar on any of my 2 monitors.. Hrm.. Is it black but on? Or on standby? Can you move a window onto it?

yeah, if the box is not checked, the monitor just goes on stand-by. won't do anything unless i attach it.

I'm assuming it's one of the monitors on DVI/VGA?

yeah, one of each

Hmm.. I'll sleep on it and get back to you.. Hopefully in the meantime someone will come up with ideas too
