Selected files won't highlight in browser

So when I’m using Ardour and I open up the browser to import audio files or open sessions, selected files won’t highlight when I click on them. They get selected and I can preview them fine, but they won’t highlight. It’s a minor nuisance, but irritating enough when you’re sifting through a large library of samples and such. I’m running the Mac OS X Native Ardour 2.7.1 on a Macbook Pro, Leopard 10.5.6. I wanted to post this here to make sure it wasn’t some idiot thing I was doing before putting it in the bug-tracker.
