Problem with Action IPO's

I have a problem with my Action IPO’s. When I add new action keys the Action IPO curves gets like a damn rollercoaster… The keyhandles gets very long. Have’nt noticed this before. Is there some way I can prevent this. I would prefered more straight lines.

I don’t know if this is your problem but when i was making a game the ipos would changed everytime you went into a game and out or pressed ctrl-a and exited. I wanted to know what has happening too.

I’ve had the same problem before. I found a solution once but forgot it now. Try hitting the button that points diagonally up right in the ipo window. I think it’s called interpolation or something like that. Hope that helps.
