I have attached the sample video of the problem which i have described earlier.
Spine imagesheet Problem
You aren't setting any translate keys on some of the animations, make sure you at least set translation on the first frame else it will use the information from the previous animation you had running.
You can also try doing
skeleton.setToSetupPose;
Each time you switch animations that might be enough to fix it.

There is no change , its still the same. Give me some other solutions. I request you to run in the corona simulator.
Is there any solution for the problem which i have described.
Nate just got back from his vacation and is now going through all emails and forum threads. Personally I've been unable to find the cause for this but hopefully Nate can shed some light on it. Sorry for the wait.

Waiting is not a big issue, but if i didnt get the solution , i would be really disappointed . 
Hi nate,
Is there any update for corona ?
Nate is updating the runtimes as we speak, should be an update for corona soon.
