Moochie - I am flattered that you’re honored! - not sure what I did to deserve that, but thanks anyway! :*)
I was going to email Pixologic, but figured I’d save some time trying a couple of forums first - I was forgeting about the closeness of ZB3 - that might explain how long I waited for serials.
Baz - long time no talkie! - yeah, finally moved from my G5 to an Intel, and decided to go for the 8-core as soon as I saw the first Cinebench results - it renders at 4x my dual 2.5! - nice 
I confess (sheepishly) after posting this thread, I decided to search for ‘Universal Binaries’ and discovered the extent of the problem! - i"ll persevere with the force quite/relaunch issue anyway, or maybe I’ll just stick with the existing copy on the G5 until ZB3 arrives. When exactly is that scheduled for anyway?
I am going to install XPPro on a separate volume too, although I hadn’t really thought about it specifically for ZB - are there any advantages?
I am hoping that Vue 6 Infinite might be a tad more stable than on OSX, where it can crash and take down the entire system! 
Anyway… 
Thanks for the pointers guys!
Cheers
Adam
