Same with me. I had a Picasa account and upgraded to 3.9 for the Mac and next thing I know it is sucking all my iPhotos into Picasa. This is HUGE VIOLATION OF MY PRIVACY. I did not give permission to Google for this to happen. Furthermore, my new Picasa account is crushed under a ton of photos I can't find my way through. This doesn't work! I just wanted to share some 30 photos of a trip I took and now I can't at least on Picasa and Google has photos I never intended them to have.
