As the author noted, this is Release Candidate software. Bugs like this are supposed to get ironed out here before it is released to market.

These kinds of bugs can often be difficult to catch because when I am debugging things, I often click through dialogs without really reading them. Of course they say what they're supposed to (and it makes sense), because I wrote them!

It's like having someone else proof-read a paper. If not, you'll just fill in the holes yourself.
