I came home from work yesterday to find my taskbar was two lines high instead of the usual one line. My wife was not home for me to find out if she had done anything. I was able to restore the size by opening taskbar properties, unchecking the Quick Launch button, click ok, then rechecking the box. This morning, after a reboot, I find the same two line taskbar, but my little trick does not work now. When I uncheck and recheck the Quick Launch button in Properties, I wind up with the same two line taskbar. I can adjust the size of the taskbar up to as many lines as I wish and back again, but cannot reduce it to a single line. I also find that I'm unable to move the separator (the seven dots thing that usually is to the right of the quick launch icons). All my quick launch icons are to the right of the separator, not to the left as I'd expect. I cannot move the quick launch icons anywhere.
I'm running XP Pro SP2
