By every evidence, there are far fewer problems with Poser 6 than there are with Poser 5/SR4. For those currently using Poser4 or ProPack (or earlier,) I would strongly recommend skipping P5 entirely and investing in P6. After assessing the mostly-positive response to the P6 release, I bought it last week, and am very happy I did. I was planning on waiting longer, but after just a few hours of tinkering with it, chose to move all my content to P6 and uninstall P5. I hope this positive perspective will have some influence on those who are "on the fence." Economic considerations come first, but it would be too bad if some folks prohibit themselves from upgrading based on false impressions or the negativity of a small minority. P6 is great. There are minor bugs which appear to vary depending upon one's computer configuration, but I haven't encountered anything yet that made me sorry I upgraded.Quite the opposite.
