I haven't bothered to upgrade to 4.5 - but when running the Beta, plugging in the iphone would launch C1 4 to import the pics from the phone - it was so annoying. I haven't upgraded for other reasons - but I can't believe that there isn't a way to disable that function.
From the Finder, launch Image Capture (Applications>Image Capture).
Pull down the menu Image Capture>Preferences.
From the command: When a camera is connected, Open: Select
No Application.
That will disable it. Even if it is pointing to iPhoto, C1 Pro seems to launch the importer. It must be set to
No Application.
