IPhoto'09 and Snow Leopard

Question

I just installed Snow Leopard and when I tried to use iPhoto's slideshow, it freezes. The slideshow feature does not work any more.
I tried deleting the iPhoto preference file, and nothing...
I Created a new account and made an iPhoto Library there, Imported some pics and the problem is still there
Can anyone help me with this problem ?
Thanks

Answer 1

I'm having similar problems editing photo with the following characteristics:
(1) scanned photographs imported into iPhoto as jpeg files,
(2) photos imported into iPhoto as tiff files
(3) photos from an iPhone
(4) photos that were in iPhoto before upgrading to Snow Leopard, that were editable, but now are not.
This problem occurred after upgrading to Snow Leopard.
Other symptoms include:
(1) When editing a photo, the screen goes blank, and it is impossible to see the photo being edited.
(2) If the screen is blank, then choosing the "slider" for size, the preview of the thumbnail of the photo is visible showing the window inside the area of the photo being edited, but the larger editing window remains blank;
(3) If a photograph is cropped in a strange shape, such as 1 inch by 7 inches, then the resulting photo stretches and distorts to fit into the cropped area, instead of simply being cropped;
(4) If a photograph being edited presents a blank space, then choosing "crop" will sometimes make the photo show up, but after the crop is made, the photo "jumps back" to what it originally was;
(5) For photos that are visible in the editing window, none of the effects work. (contrast, saturation, sharpness, etc. --- none have any effect).
(6) If a photo is exported as a tiff file then re-imported, then still the tiff file will not edit.
Note that I attempted to edit a few exported photos using Ohana's "Funtastic Photos" software, and the editing works fine. Therefore, I have concluded that:
Conclusion: The upgrade to Snow Leopard has disabled iPhoto 8.1 (415)'s editing capabilities.
