Subject: Bug in acceled Xpmac?

It looks like the accelerated Xpmac that was released in January may have
a bug in mouse handling.

I was working on a small epplet for one button mouse users to make better
use of enlightenment. When using the version of Xpmac that shipped with
LinuxPPC 1999 Q1 it worked fine. But when using the recent accelerated
version, the mouse functionality wouldn't change.

XGetPointerMapping returns the values that were set, but it doesn't seem
to be updating the way it handles the button.

Has anyone else seen similar behavior or know of a fix? I attached the
source of my program for anyone interested in trying it out.
