Animating Screws Up

Hey I’ve been having a problem with all of the unity 3.x.x and it is that when I try to animate it justs JUMPS!! for example while im trying to animate I try rotating it a little bit and it snaps back to the original so I try a little further and it JUMPS and screws my whole animating work and it has been doing this ever since the Unity 3.x.x version so I would like to know how to fix it there is another problem but ill post that if this is ever fixed.
Thanks!

So I guess nobody knows???

Hard to say anything from this description. Can you post a video? or give more details.

If I were to post a video where would I post it? and thanks for replying
