This one's a little different.
I started a server, and I didn't find any RTB prefs! Confused, I checked addons again, and I found this little gremlin called:
Support_Preferences
Space occupied was 2 bytes. I tried opening it but it didn't let me.
I removed it, confused on how it appeared.
Started server again, still no prefs.
I checked my addons folder again, and support_preferences was still there!
Any help?
