Attached Link: Archeologists Episode 3: Our Jobs Are Rad

Hey guys,

I'm doing a lot of animating - using poser as a source of intentionally lo-fi comedy creation. (Link to latest video attached). But I keep running into this weird problem. I'll use the talk designer on a character, then want to go in and tweak face expressions. But when it do, things get Weird Town. If half way through the segment i hit a key frame on the characters head I would assume that anything I do after won't affect anything before. But then i run into situations where my dude is slowly lifting his eyebrows for 15 seconds. Maybe I'm doing it wrong?

DOes this make sense? I apologize. It's a little hard to describe.
