Does anyone know why every new version of BOINC screws up Little Snitch (or vise versa) such that no matter how many times you tell Little Snitch to let BOINC access the web, it won't stick?

Even if you manually edit the rule set for BOINC (all relevant apps) in Little Snitch to allow it to knock itself out, every time you run the screen saver version of BOINC, the Little Snitch dialogue pops up asking to let it, i.e.: BOINCmanager, connect to the web. You enter, "yes, permanently", and it pops up again. This keeps on going until you give up and select "yes, until quit", and it goes away, for now.

If you aren't there and it tries to connect to the web, generates the Little Snitch dialogue request and you don't click 'yes, until quit', the screen saver engine will freeze up and you have to restart your machine!!! That's the first and *only* time I have ever had to restart OS X 10.3-5 short of an update!

My guess is that there is some sloppy hand over going on between the various "boinc", "ScreenSaverEngine" and "BOINCmanager" apps, such that Little Snitch is confused playing chase-the-squirrel-who-was-it-who-asked-to-go-out-onto-the-web...

But it's gotten to the point when every new version of BOINC means I have to endure days of random grief spent trying to get this @!*%^ problem fixed on my network of clients, so I am not running BOINC any more until its sorted.

The BOINC daemon (BOINC) needs to access the web on ports 80 (http) and 443 (https). BOINC also needs to act as a server on port 31416. BOINC Manager needs to access the network (either local loop back 127.0.0.1 or the LAN) on port 31416 to access BOINC. BOINCCmd is a manager and needs the same access as BOINC Manager.
