Useless poll as many of us run numerous versions. Everyone who upgrades Poser ends up with multiple versions. What they had before the upgrade and what you have afterward. I run 7 versions over 4 different computers and 3 different operating systems as I like to be able to trouble shoot stuff and write tutorials that are of use to folk. This poll is not going to give you any real info about a lot of Poser users as you can see from the comments above.
