I was led here looking for an answer to why, in Terminal, my three button mouse was not doing copy-on-select and pasting when the middle mouse button was pressed. (I think this is described by some as X-windows behavior, but it always used to work on my old 10.3.9 Mac using tcsh.)
The answer (which I found here: http://discussions.apple.com/message.jspa?messageID=6083729) for Snow Leopard anyway, is that the Mouse needs to be configured in System Preferences such that the middle mouse button is designated as Button 3.
Hope this helps someone else.
