Poodle,

Are you sure your program is actually "Locking Up" or is it maybe just taking a long time?

I tried using the Firefly Rendering with everything checked, presuming it to be "full bells and whistles".

The rendering process actually took 40 minutes.

I thought the program had locked, but when I checked my Task Manager, saw it was still running.

Heck of a long time to wait, but the finished product looks stunning.
