Denis - I use the following rather convoluted method with OS 10.3.8,  
Illustrator CS, and R2.0.1.

command-c copies a figure from the quartz window.  Open this file in  
preview and export it as a pdf file (don't know why i do this....).   
use illustrator, and the command <place> from the file menu to insert  
it in a new document.  Choose <save for microsoft office> from the file  
menu in illustrator. this produces a png file that plays nicely, cross  
platform, with Word and PP. variations abound, but the goal is to get  
something presentable in illustrator and use its save for office  

I noticed that preview has a png choice from export, but I've not yet  
played around with its options to see if I can get the same quality  
that the save for Microsoft Office option produces in Illustrator.
