BUG? buttons do not redraw?

I'm using build 514 on XP fully patched. VS 2010 B2 (haven't put RC on this machine yet).

Seems like if I click on a button in the ribbon status bar, it sticks in the "hot" state even when I mouse off.

Here is my status bar XAML. I'm not doing anything in the code behind. When I click on the "Goto page" button and mouse off, it stays in the "hot state", same for the two repeat buttons on the slider. Not until I click on something else that takes focus do these 3 buttons redraw. The slider thumb works fine. The application button, etc. all seem to work fine too. I tried the sample browser document editor and it doesn't seem to have this problem, but I haven't really done anything, so I dunno whats causing it to stick in the hot state.
