Bought new MBA13. Still have SL on my MBP15 . OS X Lion is driving me crazy. More user prompts than Windows :-s 1. Open Mac Mail 2. Click on PDF attachment 3. Rotate attachment (because it was scanned in the horizontal direction) 4. Lion dialog "blah blah email attachment blah blah. Duplicate. Unlock. Cancel." 5. Lol wut? 6. Curse I don't want some extra dialog box every time I open a PDF. I'm an engineer. I open hundereds of PDF schematics every day. And rotate them. I've recompile Linux kernels, but the dialog box is not obvious (to me) as to what's going on - there is no way I'm upgrading my mother's Mac to Lion. She'll be scared to use the machine again. I've turned off the Versioning in Time Machine, but it doesn't stop the stop dialog box *every time I do something with a PDF*. Can anyone help?
