The rich editor can also be a mite buggy. I'm on the beta tester discussion list, and I suspect you'll see an update on this and other irregularities before long.
In saying that, however, I have two copies of WordPress installed, because my site http://www.macnightowl.com has two databases. So I did it manually, and it takes only a few minutes either way. However, performance has been just fine -- so far at least.
