I have a G4 DP 500 (Gigabit Ethernet) and have just recently started running BOINC Menubar 0.1b. My mac has had 4 kernal panics since starting running it.

The most recent had this in the system log:

There is also the fact that it doesn't know how to play nice with dial-up connections - if it is not connected to the net when needing to send a result it quickly escalates to e.g. deferring 4 days 10 hours. It would be handy if BOINC Menubar had a "Send results now" button.
