ok, here are two images. The rotation is set to world. All rotations are at 10. Then, I click on the y rotation handle to select it, rotate, and as you can see all the channels are affected.
If I select the channel in the channel box and drag the value, this doesn't happen. When it highlights it this way, it actually looks as if it is selecting a hanldle that is slightly of the axis of those you can see - does doing it this way defauls to local, or gimbal or something?
