I purchased a new MacBook Pro (i7, 2.66 GHz Intel, Mac OSX 10.6.3) recently and am having frequent issue where I have PM running 4.6.4, put cards in to the Lexar 800 readers, have the ingest dialogue pop up automatically, but nothing shows up in the Source Paths (even after hitting rescan).
If I ingest by folders from the cards, it works fine, but it's an extra step I'd obviously prefer to avoid when working under deadline.
The problem only resolves itself when I restart the computer, but then will reappear at random.
