Tiger Bits: QuickTime Nag
This is a bit annoying: After updating to Tiger, I lost my QuickTime Pro registration and have to purchase a new license to get Pro working again (even though I own all of Apple's Pro Video apps, albeit in their pre-Tiger incarnations). So fine. I'll eventually buy QuickTime Pro.
In the meantime, whenever you launch QuickTime regular, all the Menus list all the pro features, grayed out with a big PRO right next to them. This is a software upgrade-me-nag, imho, and I don't like it one bit.
The fact that I at one point paid for the full Pro version of QuickTime and my old license is no longer good in Tiger makes this nag all the more annoying.
