Dimensioning and "Smart Move" on my mouse

Have any of you found a option turn turn off smart move justfor drafting?

My problem with 2008 is this:
I use the smart dimension tool, pick an edge, pick the other edge,place the dimension where I want it to be on the drawing, and thenmy mouse software decides that I really want my mouse pointer inthe bottom left of my screen on the property manager.

The only way I have been able to avoid this is by unchecking theSmart Move box on my mouse software.
