Hi Kirk, I have sent a crash report. To recap: PM 4.6.7 beta crashed on me two times, each time it was few seconds after initiating a second FTP transfer (or third, am not sure). First FTP transfer went fine, several other times all transfers went fine, two times it crashed on subsequent transfers.
OS X 10.6.6 (upgraded last night), I am not sure at the moment if the first crash had still been on 10.6.5 or not.
