Not owning either Bryce 5.5 or Studio, I was unaware that you needed Studio to run Bryce. If that's true, it was a lunkheaded idea on somebody's part to link the two softwares together like that. Probably somebody in marketing's bright idea. As usual, leave it to somebody in marketing to screw up a good thing. Has anybody else had this problem, or has this been common knowledg for some time? I may reconsider buying 5.5...or even 6 when...if...it comes out.
