I bought QuickTime Pro and, now that I've upgraded to QuickTime 6.3, do I still have QuickTime Pro?

The changes with QuickTime Pro are subtle. How can you tell if you have QuickTime Pro on your Mac?

[Uncle Skeleton]

they're not that subtle. if you can cut/copy/paste or export or do any editing at all, you have pro

Go to Preferences > Registration. If you have Pro, it will say so in the dialogue box.

Normally your Pro registration will survive an upgrade.

as a counter example, if you have QT 6 and you enter a serial for QTPro 5, it will say in the registration that you have "QT 5 Pro Player Edition" or something, but all that does is disable the startup nag, it does not enable the editing features
