Help with animations

Hi everyone,

I am trying to open a .xyz file containing several molecules in it. This file have been downloaded from a web page (ChemTube3D). My idea is to load this file with the animation extension in order to create an .avi file afterward.
The problem comes when I try to open the .xyz file from the ‘animation’ window. The extension is not recognised.

I don’t know whether I am doing something wrong or perhaps is this is just not possible. I’m using a MacBook CD2 intel and 0.9.7 varsion. Any suggestions?
