I updated from a SlimServer 6.1 (Nightly June 15) into 6.1b1.
I couldn't get to the firmware (rev. 14) update process related to SqueezeNetwork beta as SlimServer doesn't stay on for more than 30 seconds.
Emptied Firefox cache, trashed SlimServer folder, cache, log, prefs...etc Re-installed 6.1b1 : same situation.

I downgraded to SlimServer 6.1 (Nightly June 15 / firmware rev. 13) on which I cannot switch to French User Interface. Firefox hangs / freezes after trying this language change and SlimServer stops.

Configuration:
PowerBook G4 / 867 Mhz - Mac OS X 10.2.8 - 256 Mb Ram
SlimServer 6.1 (Nightly June 15) / Firmware rev. 13
and
SlimServer 6.1b1

BTW : How can I completely remove SlimServer from the System Preferences pane to perform a clean install ?
