Hi everyone.

I've installed the msttcore-fonts packet, and for some reason all my desktop fonts automatically changed to another (very ugly) ones.
This ugliness is everywhere - in Firefox, in Leafpad, in the xfce-terminal, etc.
I have no idea why installing a font triggers switching to it, but I hope that I still can revert to the old fonts I had.
Can anyone who has XFCE please look up the used fonts and tell me the names? Or maybe tell me some magic command that will restore all fonts to their defaults (and preferably lock them from future change)?
