FFP not recognizing restart, and other problems.

I have FFP 1.5.0.7 and to run FFP i have to open the file twice to start FFP. and after closing firefox i open task manager and FFP is still running after FF closes, i think this is related to FFP not recognizing that firefox hasn't restarted, also the themes are not applied after it is 'restarted'. i tried something that was in another post i deleted extension.rdf and that seems to have fix some of the problems up. but there is still the fact that Firefoxportable doesn't close by it's self. can you help me?
