~1 year ago, I bought a _3-button_ Mouse Systems mouse for my PC... It also
came with an ?aluminum? mouse board.  The date of manufacture, I think, was
sometime in 1991.  Just a couple of questions on the general subject-- what is
the third (middle) button good for?  I have read the docs, but can't seem to
find anything pertinent.

BTW-- I previously had a mechanical mouse that didn't work worth s**t.  To
anyone out there cursing your current mouse, you might want to look into one of
Mouse System's optical mice... Pure heaven after my previous mech. one!!!
