I have a number of different versions of Apo on my desktop at the moment, including the original (Apo 1). Within the Apo 2 sphere there are the Mark Townsend versions (through 2.02) and the betas (2.03 a-c) The betas are simple .exe files that can be included in the Apo 2 folder (with shortcuts if you want) and don't overwrite Mark's originals, so there is no reason not to set them up. I also have something called 2.02z which is a beta that seems to have gone down a separate pathway, lol. I agree that there are several problems with the beta versions and compatability is only one of them. They also don't allow some of the same ways of handling the transforms so that they lose some valuable techniques. For example, they no longer allow you to click/shift-click on the triangles to make them enlarge/shrink all around, substituting a scaling function that is a bit clumsier, and doesn't give the same results.
