You should not have state 0x2000 with alt. You should have 0x8, and
there's no reason the states should be different. I'm not treating
the two any differently.
Do you have a special ~/.Xmodmap (run 'xmodmap' at the terminal and
tell me what it says)? What's your OSX keyboard layout?

It is correct that up to and including 2.3.0 it was state 0x0, but all
those versions had a bug which I'm trying to address, the emulated
button click was always a "modifier-release, down, up, modifier press"
on the mouse-down. There was no way to "hold" button2 or button3.
Yes, those did "release" the modifier, but my reason for not doing
this in the beta I just released was that it was more "correct" with
respect to the hardware state, was easier to code, and the other way
was just as wrong in my mind. As you read in my earlier post, I want
to change that so the default is to reset the modifiers, but you have
to understand it's not a trivial problem. Consider:
cmd-down
button1-down # emulated as (cmd-up, button3-down, cmd-down)
a-down # this should be cmd-a since command is down
a-up
button1-up # emulated as (cmd-up, button3-down, cmd-down)
versus
cmd-down
button1-down # emulated as (cmd-up, button3-down, cmd-down)
cmd-up
a-down # this should be a since command is down
a-up
button1-up # needs to be emulated as button3-down without cmd-up/
cmd-down
This gets even more complicated in the logic once we add in the
possibility that l/r modifiers can be differentiated between... so
just give me a little while to figure out a clean way to do this.
In the mean time, I'm more concerned about why your alt
