I have a strange problem with my mouse. I noticed that the sensitivity going up the screen is less than 10% of the sensitivity going down the screen or left/right. To be specific - to move the mouse pointer from top to bottom of my screen, or from one side to the other takes about 2" of movement on my mouse pad. However if I move 2" in a VERTICAL direction on my mouse pad the mouse pointer moves only 1/4" to 1/2" on my screen.
Why this reduced sensitivity in the vertical direction. I am assuming it is a software problem because I substituted another mouse and got the same effect.
I am running on Windows 98. I am using a Microsft serial mouse with the Microsoft Standard Serial Mouse Driver dated 5-6-1998.
