Hi, i´m new in this forum and maybe this is not the correct thread D: Also, I´m pretty new to animating with Flash. I recently upgraded to CS4 (i´ve been using CS3) and when I tried to do a simple **Classic Tween** with a symbol, it **started shaking in the .swf**. I mean, I had a symbol in the frame one. I copied and pasted it in the same place in the frame 15, for example, add a Classic Tween in the first frame, and when I exported the animation, **the symbol didn´t stay quiet in it´s place** (since there is no movement), **but instead it just started to shake in its place**. I figured out it was some bug on CS4 or that I messed up with the tweening, so **I reinstalled the CS3 and tried to do the same animation with a simple Motion Tween, but it just keep happening the same thing!**. The problem is not reduced to Motion Tweens with no movement into them. **I tested it making the symbol go from a place to another, and moving several symbols (on diferent layers)**. The problem persists and I don´t know what to do D: I posted it on the CS3 forum because, since it´s the version I´m using now, I would need help solving this on this version. **Thank you for taking the time to read this and for helping me in any way you can**. I´m sorry for my crappy English, but it´s not my first language 😛 Aresin PS.: If you rather look at the .fla, just ask me for it and I´ll attach it. PS.2: The problem does not appear only in the .swf, both keyframes in the tween, int the .fla, appear to be sigthly different (no mather if I copy/paste it). ;\_;
