Finally stepping in... ;) Hi folks, as wabe already mentioned I'm a Mac person, too. My machine's specs are as follows: G4 MP 500 (Dual 500) with original setup (ATI RagePro 128), 1.2 GB RAM, 2 x 20 GB internal HD, 120 GB external Firewire HD, Mac OS 10.3.3. Vue 4.2 and Vue Pro (Version 268493 I guess, though I have to recheck, when I get home) I experienced various crashing problems after upgrading to newer versions of Vue Pro. Mainly while importing Poser figures. So I switched back to an older version which I lukily kept on my backup HD. Again, I'll recheck with the correct versions of Vue4 and VuePro when I come home and let you know. Right now Vue and VuePro run pretty stable on my mac. Cheers, Phil
