How to disable mouse wheel (buttons)

[Konstantin N. Kudin]

 Hi everybody

 I am trying to disable a mouse wheel under cygwin/xfree and can't find
anything anywhere on how to do that. Basically, the wheel acts like
buttons 2, 4, and 5. Scrolling the wheel is translated into buttons 4 and
5, and that crashes one of my applications. I would like to simply disable
that under cygwin/xfree and keep it elsewhere (under Windows).  However,
there seem to be no file XF86config anywhere which could be used to set
the number of buttons to 3.

 Any help is appreciated.

 Thanks!
