Summary: Wine 1.3.15 breaks side mouse buttons in Team Fortress
                    2.
           Product: Wine
           Version: 1.3.15
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In wine 1.3.14, my side mouse buttons in Team Fortress 2 worked fine. Upon
upgrading to wine 1.3.15, they were no longer recognized at all; they act like
nothing is pressed when in either the key configuration or in-game. Reverting
to 1.3.14 makes them work again.

Complete and likely unnecessary info: Arch Linux 64 bit, rolling release up to
date as of today, March 5th, with the liquorix kernel. Testing/unstable
repositories are not in use. Logitech g5 mouse.
