Remove last frame which is same as first when rotating objects

Hello, great to see the new version out. My question is how to remove the last frame (or similar action) when I rotate an object. I always get the hickup as it starts again. In flash they decribe this as the last frame being the same as the first so you are in reality playing this frame twice in a row which causes the hickup, & in flash you just delete the last frame but Ive noticed you cannot do this in 3dfa. I have tried increasing the rotation from 360 degrees over 1 second to 36000 degrees over 100 seconds but I'm sure there must be a better way. Does anyone have an idea on this, I'm sure someone else has come across the same problem. I must say 3dfa is a great product to have in a web designers arsenal. Thanks for any help.
