xantor, This is similar to the ongoing discussion about updating the poser code. If they did update it, there's no guarantee of backwards compatibility. In addition, the hacks we take for granted now, might disappear forever with new code. If CL/EF were writing poser from the toes up, they might well consider going binary. I don't envy them. They're between a rock and a hard place. If they do a rewrite, they're damned. If they don't, they're damned. And if they don't rewrite, things like the lack of multiple undo will remain a thorn in their side for all time. mac
