Image shift problem

[stygian]

I'm having difficulty with images shifting even though they are perfectly aligned.
It seems to happen with an alpha tween the most. Have checked and double-checked, but those images are correct - what's causing the shift? It's almost like a mirage effect.
Also, if another layer is having a tween, sometimes it disruptes the layer it overlaps, too. Any suggestions?
Thanks

Try not using 0% and 100%... more like 1% and 98% or 99% in your tweens, that might help!
