Hi Ico
Ive got it working and have loaded some libraries, Gem, Gridflow, Zexy, pdp
- however PD crashes out when I ctrl-1 to put an object on the canvas.
I've done a backtrace (thanks Mathieu for the tip previously) with the
following results:

A debugging session is active.

Quit anyway? (y or n) y

Thanks for your help with this! It's a great package to work from
Cheers
