Aperture 3 and iWeb
And then I found this note by nikonshooter on this Apple Discussion board post:
I found this on Flickr from Distant mirroe had this problem a few days ago, and found the following solution:Create a new Aperture library (just name it Temp or something irrelevant), then switch back to your main library. Then you can delete Temp. It worked for me, YMMV.
This tip worked for me. I’m thinking that there’s something which gets initialised in Aperture when a new library is created. My current library was an import from Aperture 2, so therein may lie the problem.
