Mouse behaviour, Studio 4.5, Windows 8 (64 bit), VMware Fusion

Hello,

I wonder if anyone has seen this issue and can point me to a solution. I am trying to run DAZ Studio 4.5 Pro on Windows 8 (64 bit) which is running inside a virtual machine in VMware Fusion 5. Fusion 5 comes with OpenGL 2.1, and Studio claims everything is OK (see output "Current Hardware Features" further below). It starts up w/o any issue and displays genesis. The problems arise when I try any of the mouse operations in view port (orbit, rotate, pan, zoom) ... the image just jumps around erratically, apparently completely unrelated to what I do with the trackpad (which is handed through to the virtual machine as a 2-button mouse). The same issue shows up when I try to rotate the whole figure (select all, go to "Pose & Animate", General -> Transforms -> Rotation -> X Rotation" for example. The slider just jumps around).

Posing individual limbs works fine, though.

--> Any ideas?

Cheers,
Chris
