IPOs Have Vanished

While in pose mode, I select a bone in my armature. At frame 1, a RotSize keyframe is inserted.

Changing the position of the same bone and the counter to frame 31, another RotSize keyframe is inserted.

With an IPO window open to Object view, no ipo curves appear. This is different from my previous work with an earlier iteration of the same model where I was able to edit the ipo curves easily.

Why would the IPO curves be invisible?

because it’s not the object ipo that gets set when you manipulate a bone in pose mode, it’s the action ipo. go down to the pullup menu and change it to ‘action’.
