My biggest beefs with Aperture 2 are its sluggishness and bugs, which seem to come out with a lot of raw photos loaded into the library. I am not inclined to waste time importing thousands of photos into the Aperture 3 demo, so I'm hoping to get reports from those of you have have already purchased the program and have loaded it up with lots of raw files. If you are one of these people: 1) Are you ever getting that red "file type unsupported" screen? This one comes up every so often in Aperture 2 and requires a relaunch to correct it. 2) Is it still like wading through molasses to tug on the adjustment sliders? 3) Is there any other annoying or buggy behavior that you've noticed? Many thanks!
