Q: Pictures round-tripped to Elements are correct in Browser but not in Viewer

Hi all,

This is a bit weird.  When I edit a photo in Photoshop Elements 10 (and then "save" and thereby send it back to Aperture), the edited photo shows up correctly edited in the Aperture browser, but it's uncorrected in the viewer.  I always use the "Split View," and so the corrected photo appears among the thumbnails, but when I click on it, the photo in the viewer doesn't have the PSE corrections!  Weird.  This worked well for many many months, but now doesn't seem to work.  If I close out of Aperture and come back in, the photos are correct in the viewer and the browser.  Any ideas?  (These are correctly saved -- not "saved as" -- in Photoshop.  And it worked well for months.  No need to discuss saving and round-tripping.)  Thank you!
