Generally, Poser 4 has been working fine for me in Mac OS X all along, including 10.2. However, there's one "quirk"... One of the things I loved about moving Poser 4 from Mac OS 9 to X was that it no longer could lock up the whole bloody system while it rendered -- I could still switch away from Classic and get work done. Except it was never quite smooth. The dock was hidden, and CMD-TAB didn't switch. Except that if I hit CMD-TAB with my cursor at the bottom of the screen the dock would pop up. Yeah, weird. Well, with 10.2, this doesn't work anymore. I did find, however, the I could work around it by adding another hack to the equation... if I bring up the Force Quit dialog and select another application (but don't quit anything) and THEN do the CMD-TAB/dock thing... (Sheesh.) While it's true that Poser was always a "bad citizen" (when rendering), this is basically a Classic problem rather than a Poser problem. Classic is just a Mac OS X application and ought to behave like one. But heck, Poser is the only thing I ever use Classic for, and it's a minor annoyance once I found the workaround. And "soon" we'll know when we can look forward to not worrying about this anymore. (If you believe the web page...)
