RC1 will crash for me using a Mac, with Mavericks..
..if I have a Tour open, built the Tour, closed the preview then go to Home, "Create empty pano project"... Add cube faces.... Crash...
..if I use the Undo... Crash...
..if I press the - on this line marked with no info image box displayed.. I added lines then removed them, but they do not completely remove, they can leave just the option to remove. Once I press the - RC1 will crash..
A tip when added images to your gallery.. Add image, then press +, PTP will now then were you images are located. Keep pressing the + ONLY after the images has been added.. This is true with both the small and main Gallery....
Destiny..
PS.. I cannot add the entire crash report here so I can send if requested...
