Summary: WaitForInputIdle doesn't return for specific
                    application (infinite loop?)
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

There is application called Injection Launcher that launches Ultima Online
(game) client and then hacks it. When using Wine, Injection Launcher doesn't
notice that client started.

Is uses something like:
if (WaitForInputIdle(pi.hProcess, INFINITE) != 0)
{
    api_error("Failed waiting for client window to open");
    error_stage(STAGE_STARTCLIENT);
    return 0;
}

This bug is present in Wine since "ever" and exists in git.
