Mouse Scroll Wheel Problem

[Charlie McVeigh]

 I have an IBM Thinkpad T42 that was running FC5 and an IBM optical
 scrollpoint USB mouse with an PS/2 adapter plugged into my laptop. The
 scroll feature of the mouse was working fine without any problems. Stupidly, I
 decided that I didn't like the scroll button on the IBM scrollpoint
 mouse, and installed an old Logitech M-S48a mouse with a real scroll
 wheel to use instead. From that point on mouse scrolling for me has been
 broken.

 If I turn the mouse wheel the active window, it will scroll 2 lines and
 then stop no matter how much I turn the scroll wheel. I have even tried
 to re-install the IBM scrollpoint mouse and I get the same behavior with
 that mouse as well. A couple of lines will scroll in the active window
 but that is it.

 I upgraded to FC6 this past weekend thinking that my mouse problem might
 be fixed but I am still getting the same behavior with both the Logitech
 and the IBM mouse.

 By the way, the touchpad and Track Point mice built into the laptop work
 with no problems.

 I would be very appreciative of any suggestions that the wise ones on
 this board might have to resolve my problem.

 The mouse parameters in my xorg.conf are as follows:

 Section "InputDevice"
         Identifier  "Mouse0"
         Driver      "mouse"
         Option      "Protocol" "IMPS/2"
         Option      "Device" "/dev/input/mice"
         Option      "ZAxisMapping" "4 5"
         Option      "Emulate3Buttons" "yes"
 EndSection

 Section "InputDevice"
         Identifier  "Synaptics"
         Driver      "synaptics"
         Option      "Device" "/dev/input/mice"
         Option      "Protocol" "auto-dev"
         Option      "Emulate3Buttons" "yes"
 EndSection


Thanks.
