Nope, she works fine with ProPack, you will need a lot of ram though, I'm running with 512mb & it can be very slow loading Vicky & posing her. Just make sure you have either the latest version of Poser 4 (4.03), or you get the patch from Curiouslabs, and the latest patch for ProPack. I can't help you with the lightwave question but ProPack does ask if you want to install the lightwave plug in during installation. Unfortunately I don't have lightwave. You could try the lightwave forum, someone there may know
