Made a birthday card for daughter-in-law in Excel. Then, to send to iPhoto, command-P - under PDF - "Save PDF" to desktop. Then, attempted to put into iPhoto. Message = Unreadable file window - "The following file could not be imported. The file is in an unrecognizable format." Then lists the file, which is a "... .pdf" Have inserted dozens of PDF's into iPhoto before. Is Lion causing this?

Any ideas?
