Waking up OS X Lion

[VydorScope]

So yesterday I decided to do the upgrade from Snow Leopard to Lion vai the App Store, and it took a long while but seems to have gone off with out a hitch but there is one change that I am not sure I like or how to fix. In OS X Snow Leopard I could wake my iMac back up by moving my trackball, but in OSX Lion only a click of the mouse button will wake it up. It is a Logitech USB track ball that I have had for years.

It is a very minor annoyance, but does anyone know how to fix it?

This is now How It Is. Annoys me as well. I'd like to just move the mouse but you have to click or hit a key.

That's interesting, the only way that i can wake my macbook with lion up is by hitting the screen brightness...
