Re: ALPS DualPoint double click bug

[Stephen Chandler Paul <cpaul@redhat.com>]

Hi! I looked at one of the recordings that was sent, and I just wanted
to clarify that the version you probably should be using to record
everything is ps2emu v0.1.2. The one that's in the master branch right
now is not entirely stable, and it's giving us a couple of problems
replaying the events on our machine. You can find the stable release
here:
