One thing I've noticed on the Pro 2010 beta is that the opengl rendering in the pose room works better for me.

I'm using an ATI mobility X1400 card in my laptop and have had some issues with it with Poser. Older drivers cause an issue with the mouse cursor - the cursor changes to the tool in use when over the work area but then sticks for several seconds before changing back to the standard arrow cursor when it's moved away from the work area, meaning I can't select a menu or another tool until it changes back. Had this with Poser 7 as well.

Later drivers and a setting in the poser.ini solved this issue but, in Poser 8, the later drivers have a knock on effect of causing the pose room preview to seemingly blur/defocus when the cursor is moved away. It's fine when working on a scene but as soon as the cursor moves away from the preview it pixelates slightly and blurs. Not a major issue so I've lived with it and it's only because of the lack of newer drivers and the fact that I'm currently using the laptop that it's there. Will be moving over to my main machine when I do my next build anyway so not an issue.

...however, with the exact same settings, I don't get this behaviour in Pro 2010 beta, even though, as I understand it, it's basically Poser 8 with some Pro features left enabled.
