Finder stealing the camera

I've been having a problem with Quartz Composer where sometimes it doesn't recognize the attached camera. I finally figured out the problem and I thought I would pass it along. If the Finder is in the multicolumn mode and you select a .qtz patch (so that it is highlighted), a preview is shown in the finder. The problem is that if the quartz patch that is previewed includes video input, then the preview steals the camera from other applications. So if you navigate to a patch file using the finder in the multicolumn mode and double click on it, quartz composer is unable to access the camera input because the Finder preview is using it. To fix this, just switch the finder to a different view such that the preview isn't visible before opening the patch.
