@Cartman: The bug of BLIde beein frozen is a z-order bug, there was a message box telling you that the changes you made could need a BLIde reboot. Sometimes this windows keeps below the modal preferences one, and BLIde seems frozen. It has been fixed for next release, if that happens again, just press SPACE or ENTER and everything will be working again.
You can disable this pop-ups on the preferences dialog, and I will improve they way they are working now, it is a little bit annoying to me too.
