I am noticing Pathfinder is frozen. I think I remember a post for a fix but I can't find it now??
+ I don't recall anyone every reporting this behavior. Pathfinder is a augmented instance of Internet Explorer; if it's truly frozen, my advice would be to reboot Windows. If it freezes again, I'd check the Windows Event Logs to see what happened at the point in time that Pathfinder froze. Interference from an incorrectly configured anti-malware application is another possibility.
