Mouse Problems

[Dai Vernon]

I seriously don't know what I did!!

While in a plan I always use my scroll button on my mouse to zoom in on objects. I place my cursor arrow on the object then scroll up to zoom in close.

Well, for some UNKNOWN reason I can't zoom in properly. Now if I zoom using the scroll button on my mouse, Chief does not zoom in to where my cursor arrow is pointing. The whole page moves. The scroll bar on the side of Chief scrolls up all over the place.

For example, I want to scoll in on a dimension. I place the cursor on the dimension and scroll up. Now I place my cursor on the dimension, scroll and I end up JUMPING to no man's land, 5 miles away. It's basically not centering/zooming in on my object.

I tested this in AutoCad and it works fine, I can draw anything, then zoom perfectly. It's not my mouse. (BTW, I'm using a logitech MX 1000 laser mouse.)

Hard to explain, I'm just praying that someone here has encountered this and knows what I did and how to fix it.

THANKS!!!!
