Removing auto easing

I have a rotating cube which I have built for a website (to loop). However it has easing applied to the keyframes. How can I remove this so the looping is smoother?

In the IPO curve editor window, select the animation curve and press E. From the menu, select “Extrapolation.” This should make the angular velocity (slope of the ipo) remain constant (as long as your keyframes are co-linear). In other words, it will make your cube rotate at the same speed until the end of the animation, no easing in and out.

Cheers Xabotage.

I am using 2.53. Slightly different windows than 2.49 but applied Linear Extrapolation and works like a dream!

Thanks again for your quick reply.
