Hm, it doesn't crash Anim8or (build 1162) for me, when just running render(); from a .txt file. But it only flashes the render screen and then goes back to the workspace, though the render progress bar keeps going even if I can't see it.
So yeah, it's definitely messed up.
Personally, I'd like to see better ASL functionality in the Scene Editor. Some way to access all of an object's data from within the scene editor (as instances, so that via ASL everything can be loaded and changed on the fly without making permanent changes to the actual object), as well as set values for controllers (who wouldn't want to make their own constraints system when animating with bones?). I could mention lots and lots more than that, but I think/hope Steve is aware of ASL's current limitations.
