There may be a reg edit that someone can point you to, sorry I do not know either. I just wanted to comment that tf3d seems to override alot of the otherwise default settable apps. I love agenda 1 also and always set it to be my default calendar, but I finally outgrew the ram hungry tf3d and wrote it off as unneccessary eyecandy I could live without. Not before I tried it for a couple years, but I'm officially over it, have tons more ram and no freeze ups, slow down, or lagginess to speak of or other tf3d related issues. And my agenda1 works a treat as default. Sorry I was no help, just wanted to comment. You might try asking over at xda, as they are quite knowledgeable if you can get them to respond nicely. cheers...
