First off, I didn't think of it. When gmax first was released, I did a little asking and a good fellow named Chris Cookson showed me this trick (and a link to the script). I have since lost the link but still have the script (which I modified a little). My machine is fast but I'm not making my own full blast figures (like Mike and Vicki or Posette) - I just make stuff; clothing and props. I just export a piece at a time.

As far as the cutting and pasting, I pay for it here. I do a Ctrl-A Ctrl-X in the listener - then a Ctrl-V in WordPad (over and over again....)
I bet that I do it while I'm sound asleep too! That is the biggest draw back - but it works and it is free.
