sharing with Twitter in Stanza

[Daephex]

I posted this earlier in the Apple forum, but wasn't exactly sure which part of the forum was best, so I'll repost here:

I know that I have my user name and password correct, but I keep getting an error while trying to share via Twitter from within Stanza:

"error posting. Ensure that your username and password are correct: unauthorized"

Any idea what's going on? I searched Google first, but just found a couple other people asking the very same question-- obviously, no answers. Big karma available to whoever can help me out!

Thanks! --DaveX
