I have been using the trial version of Aperture 3, and upgraded today to the full version by using the serial number I got with the boxed version. I then upgraded to version 3.0.2 via software update. Now, when I try to apply Presets to a photo, the presets (Quick Fixes etc) are all greyed out. Does anyone know why this might be and how I can fix it? using OS X 10.5.8 on Intel Macbook Pro. Thanks in advance. === <cough> i can answer my own question here. Will do so in the event that it helps someone else ... I had Quick Preview on. Toggles with "P".
