Cordless Mouse poor Responce

Not too sure where to find information on this but wonder if anyone here could help.

I have cordless Logitech Mouse <A HREF="http://www.logitech.com/index.cfm/products/details/CA/EN,CRID=486,CONTENTID=5060" target="_new">Navigator Duo</A> and there is a delayed responce when stopped, might be a battery saving thing?

This "delay" is not so much a delay, but more like the mouse will not go up...as it seems to go a bit left or right, even down during this "delay".

Normaly i would say this mouse and keyboard set are Excellent, but the mouse is beginning to get to me.

Is there anything that can be done to correct a delay or jitter or pause that this mouse seems to be displaying?

Test
- quickly moving the mouse up and down and pausing at the end of each direction for a split second causes this delay all the time...is that normal?

- If the mouse has been sitting in one place for more then a few seconds the same thing occurs.

the Machine i am using is an AMD64, 1G RAM, 9700pro.
The Optical Reciever is in direct line of sight, ranging from 16-24"
