Using V1.2alpha. Close all mozilla widows and there are still mozilla proccesses running.! If I then try to kill -5 the proccesses and get the feedback agent (+ core dump). Pretty sure that this should not happen but can't see that anybody else has reported it. If I don't kill the proccesses and try to run mozilla again it tells me that my profile is in use. NOTE: there is a simmalar bug to do with java processes I don't have java installed with this version so I don't think it is the same bug.
