Fedora 16 preupgraded to Fedora 17: xinput changes took away my touchscreen's right click emulation

[Rui Miguel Silva Seabra]

Hi,

I have been happily using a WeTab atom tablet with Fedora for about an
year.

In Fedora 16 I had right click emulation via xinput like this:

xinput --set-prop 9 "Evdev Third Button Emulation" 1
xinput --set-prop 9 "Evdev Third Button Emulation Threshold" 70

After holding down a finger for a short time, I got the right click
emulation.

Now, after upgrading with preupgrade to Fedora 17, it no longer works,
I mean, the values get changed and I can consult them with xinput
--list-props 9, but no emulation happens.

I'll mark this as a bug if it's not a configuration problem on my end,
for which I hope someone here can help me identify whether it's my
setup that is wrong (and how to fix it) or if I should file a bug and
against which component (libXi, kernel, xorg, etc...).

[rms at ftab ~]$ xinput --list

Thanks in advance,
