This is in the 1.6 Control Panel, although I have 1.5 and 1.4.2 installed as well. Windows XP.

When I run the Control Panel, even from an Admin account, I make changes (such as turning on tracing, show console), but when I press Apply then OK, the dialog disappears, but if I immediately open the CP again, all my changes I just made are not there. It is the way it was before I made the changes.

What is going on here?
