Summary: mouse side buttons do not work in wine when mapped to
                    gtk/qt standard
           Product: Wine
           Version: unspecified
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I recently realized my "back" button in firefox wasn't working, looked into it
and it has been remapped to mouse button 8 (back) and 9 (forward).

I found https://bugzilla.mozilla.org/show_bug.cgi?id=355477 on the subject,
quoting:
"I'm attaching a simple patch that maps X mouse buttons 8-9 to the back/forward
commands. The consensus amongst GTK+ and Qt seems to be that buttons 6-7 are
for horizontal scrolling."

However, in WINE (specifically using world of warcraft) if I can't bind
mouse4/mouse5 (what wow calls my side buttons) if I use this standard.

With this:
xmodmap -e "pointer = 1 2 3 4 5 6 7 8 9" (standard)
Firefox back/forward works perfectly, but the side mouse buttons do not
register in wow at all.

xmodmap -e "pointer = 1 2 3 4 5 8 9 6 7"
I can bind my side buttons in wow, they register as "button4/button5" in wow,
in xev they register as 6 7.  However my back button in gtk applications stops
working.
