I have been using Aperture with the Nik collection for a while now and have had no problems with it, but yesterday a problem developed that I've never seen before. The image in Aperture (thumbnail) is not updating when leaving the external editor. The effect has been added to the master, but not the thumbnail. Even more weird is that if I click browser it shows the edit in the small thumbnail, but when I click on the image it comes up with nothing. I also noticed that if I close Aperture and re-open it the thumbnail is updated.
The only thing different between now and when it was working perfectly is that both Nik and Aperture have undergone updates. If anybody is having the same problem or has a soloution I would be very grateful. I don't really want to close and re-open Aperture after every edit, but it seems to be the only way to go for now.
