Chris, I hereby nominate the Targus PAUM01U as the official 3-button mouse for PyMOL users on the go. http://www.targus.com/us/product_details.asp?sku=PAUM01U They might be too small for some, but they work great for me, at home and on the road! (plus, they color-coordinate with Ti PowerBooks) Cheers, Warren -- mailto:war...@delanoscientific.com Warren L.

Any suggestions? Thanks Chris
