Another bug I've noticed is that after the first witter oauth via the twitter website, when you've typed the number code in and pressed ok; any further attempts to add other accounts or re-auth the same account will end in that dialog box where you type the number not appearing properly. Its still drawn and the button is there, but only pops up half-way, so half the number you're trying to write is invisible, and its really hard/impossible to click on the ok button.

The only way to get it back again is to exit the app and restart it.
