Summary: GetAsyncKeyState wrong if querying process doesn't have
                    focus
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

GetAsyncKeyState doesn't return the correct key state if the focused process is
different from the process querying the key state. In Windows, the call works
regardless of focused process.

GetAsyncKeyState does a lookup in the global key_state_table in
winex11.drv/keyboard.c, and each process gets a separate instance of this table.

http://msdn2.microsoft.com/en-us/library/h90dkhs0.aspx gives two ways to
implement shared data, while vitamin on IRC mentioned this might belong in
SharedUserData.
