Hi, Nick.  Thanks for the feedback. I’m know there are some differences with 3d 
panning & zooming that could potentially be an issue, but I’m a little 
confused, though.  When you say pinch, do you mean a trackpad?  Are we still 
talking about the ThinkPad laptop here?  If so this is very interesting.  Could 
someone educate me about any current support for trackpads in windows or Linux? 
 I was not aware of any.

Garth
