Okay, I just installed Panther, and am very impressed with it. But, after awhile, when I roll my mouse over anything that should respond to a mouse rollover (dock, menus, web links), nothing happens. I can click on something in the dock and it'll work, but when I just move my mouse over it, it doesn't show a label or magnify. Same with menus. The blue highlight does not show up as I move around in a menu. When I restart, this problem goes away, but soon returns. I did a completely clean install, I don't know what gives. Anyone else have this problem?
