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.

Hi,

Yes, thjere was a serious mouse bug problem with usb mice fixed in
Xpmac rev8 and later versions.  It seems that the accelerated Xpmac
was not properly setting an accurate time for the mouse button
events.

Please try upgrading to Xpmac rev9 and try again (see
http://www.linuxppc.org/BlueG3/ for a link.

If you still have a mouse problem with Xpmac rev9, please let me
know.

Thanks,

Kevin

The problem still exists in this version. Also, this machine doesn't have
USB. It's a straight 6500/250, no upgrades or add-ons. The program just
tries to remap the first button to a different button.

The server reports making the change, but the mouse button behavior
doesn't change. I know the server is acknowledging the change, because the
program calls XGetPointerMapping to set it's initial values. Exiting the
program and starting it again reports the same values that were set at the
end of the last run.
