[After Effects 7] Easing multi-properties

Hi again! OK, this one has been bugging me forever. In the value graph editor, when you select an ordinary property, you can set keyframes to bezier interpolation and you get handy little handles. Totally normal and good. When you select a property with multiple parameters, like position or orientation, you don’t get handles. What gives? How am I supposed to manage temporal easing?? In something like Final Cut, you’re forced to adjust temporal easing in the comp window, but in AE that only controls spatial easing (which is good, and the way I’d prefer it).

What’s the deal? Is this somehow a problem with only my copy of AE? Does anyone know what I’m talking about? My copy doesn’t appear to be “Professional,” and a friend of mine doesn’t seem to have this problem, would that be the problem? This is absolutely absurd.

Thanks in advance, guys!
