Wrong Control Gets Focus in Find Dialog

Here’s a a problem that’s bothered me for a while, but I just realized what’s going on.

If I press Ctrl-F, the find dialog appears, and focus is set to the “Find” edit box. That’s perfect.

I go to the document, and do some editing (the find dialog box is still visible).

I press Ctrl-F, again, and the find dialog receives focus, but the focus is now on the Next button.

What usually happens is that I type the text I’m looking for, and wonder why it isn’t appearing in the edit box. Until today, I always worried that that text was going into the document somewhere.
