Also, the scroll speed of this widget using the trackpad is ridiculous. If I have a mouse, I can use the wheel or drag the nearly invisible scrubber (not your fault, it's the default UI for poser), but just two-finger scrolling with the trackpad goes incredibly fast no matter what setting I have for the trackpad's actual tracking. rMBP internal trackpad, two finger scrolling, USB internal connection. Fine tuning settings with BetterTouchTool has no effect. 

Is this somehow related? http://labs.byhook.com/2010/04/09/flash-mouse-wheel-support/

Was there no answer to this? I'm using Poser Pro 2012 and the tracking speed of the mouse when I'm scrolling the folders and their contents are absolutely ridiculously fast and it's driving me crazy. Is Poser is still in business?
