Had to uninstalled IntlliPoint 5.5

I found out a while ago that the IntelliPoint 5.5 software actually made the left mouse click of my new wireless mouse LESS responsive. So I installeld it, and found that my mouse back to normal.

Now I am a bit hastiate to install IntelliType Pro 5.5 for the keyboard. :-<

How come everytime I brought new hardware, including getting this Microsoft Wireless Optical Desktop 1000 , there's always some gotcha here and there :-<
