When I enter iPhoto, I usually notice that the font is noticably bigger in the Source area than it is in iTunes. Basically, it looks like the exact same size as in iCal's Calendar area. It IS NOT the Large size, but is in-between the small and large size. I have tried changing the source size and it works until I close it. When I start iPhoto back up again, it goes back to the bigger size. Is there anyway I can stop this from happening, or is this just a common bug with iPhoto?
Found the Solution Ever since I resized my iPhoto window not to take up the whole screen, I haven't had this problem. Pretty weird though...
