Uh, your whole device reboots? Just like that? I can find no reason whatsoever why it would do that... Can you launch it from x-term by typing /opt/fmms/fmms_gui.py and see if it still does that? And try to see if theres any output before it does, if it does... Uh, interesting.. might been a freak error. Even though nothing went seriously bad there should still be a log in /tmp/fmms.log, if there is, could you PM me it or drop me an email? Thanks!
