I also noticed this error since Snow Leopard. Even the latest Build of PF has this kind of bug. Any right click will hang PF for about 2 minutes. During this time I see this in the console log:
HTML Code:
Nov 20 08:40:13 NCC-74656-Voyager fseventsd[42]: SLOWDOWN: client 0x10102a400 (pid 8014) sleeping due to too many errors (num usleeps 1013)
The mentioned PID is the PF application:
HTML Code:
501 8014 204 0 0:02.79 ?? 0:09.27 /Applications/Path Finder.app/Contents/MacOS/Path Finder -psn_0_4236298
This is really annoying since it makes PF completely unusable
