At present it does not seem that abiword supports wheel mice, like the
Microsoft Intellimouse.  Worse, it seems that (accidentally) using
the wheel causes abiword to crash?  Is this behaviour reproducible?
I am so in the habit of using the wheel now that I find it all too
simple to try to use it to scroll!  I use Linux/x86 + abiword 0.7.4,
installed from .i386.rpm's.
I have a 
    Protocol    "imps/2"
    ZAxisMapping 4 5
inside my XF86Config file.  Most other apps seem to support this now.
Cheers,
Kev
