helloi'm new on this forum i'd like to say hello to everybody and i have a little problem.when i'm using the mouse wheel to zoom in or out the focus of the zoom is in the center of page and not on the cursor.how can i chage this?

It sounds like a hardware issue or driver conflict. What mouse and driver version are you using.

I don't think that's a hardware conflict because in one project the zoom is working ok but in the other project the focus of the zoom is not following the cursor and remains in the center of the page. :-??I think I adjust some settings wrong but I can't find where can I change it back.

Have you tried doing an audit on the drawing? Was the drawing in question created with the same version that you are using now? I'm just throwing things out here.  I've never heard of anything like this before from drawing to drawing. 

the projects were made with 1 or 2 days difference and is the same version of autocad. i was thinking that maybe autocad generated some error and because of that some system file suffered modifications.because if i make a new project now i'll have the same problem with zoom.

I've searched everywhere that I can thing and Google turned up no useful results. I can't find a setting anywhere that changes that in AutoCAD.  3DS max has a "zoom about mouse point" setting, but I've never been able to find anything like that in AutoCAD. Have you tried re-installing your mouse drivers? Also, Have you posted your situation on the Autodesk website?Sorry, I'm not much help. This one has me baffled.
