The P6 issue interests me, especially when any issues can be fixed by upgrading to P8, which, right now, can be done quite cheaply. I do sometimes wonder why folk want to hang onto older versions.

That said, I will admit that I bought P8 completely on a whim and was quite happy with P7. Still, now I've gotten to grips with the advances that P8 brought with it, there's no way I'd go back. I can do things with lighting and rendering now that I could only dream of with P7. Sure, P8 has it's foibles, the library always annoys me in that it takes nearly 10 minutes to get itself together when you're eager to start work, but, this can be lived with when you see the quality of the renders.

CHEERS!
