Debug window running all the time

Anyone else had this? When I start up SL, I get a DOS window appearing with loads of stuff that looks like debug info in it, and I have TWO SL entries on my taskbar - one is the real SL, the other this debug window. If I close the window, it closes SL too.

I noticed when I clicked on Advanced that "Output Debug Minidump" was ticked. I unticked it, but even after rebooting my PC every time I start up SL, the debug window appears (though the "Output Debug Minidump" is now unticked).

The debug window has lines saying things like INFO: LLCircuitData::CheckCircuitTimeout...

Anyone else having this? How do I turn it off?

Advanced / uncheck Console Window (it's near the bottom) and relog.

Thank you very much Kitty, that worked a treat
