I have an A1000 mouse with the same problem.  Basically, the button
works by depressing a little metal dimple, which touches the switch
and then pops back up.  Over time, the dimple tends to flatten out,
so it doesn't contact as well.

I opened up the button and played with the dimple a little until it
bounced better.  To do this, you have to unscrew your mouse and cut
the four little round plastic tabs that hold the button on (the four
"o"s in the following illustration):

   ____________
  |o   ____   o|
  |   /    \   |
  |  |      |  |
  |   \____/   |
  |o__________o|


Remove the metal square and the button and you'll see the dimple.  It
should be curved upward.  Remove it and curve it a little more, playing
with it on your desk to see how well it springs up, then put it back.
Put the button and the metal square back on top.  I haven't even
bothered to tape the metal square back on; the mouse works fine with
it loose (although if you shake the mouse hard or turn it upside down,
you'll have to open it up again and put the square back on--probably
better to tape it down).

Haven't had any problems since I did this (about two months ago
with the left button, one week ago with the right button).
