Summary: IM fails when edit box is a child window in a separate
                    process
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-misc
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I have a program which requires for a edit box to be a child window running in a
separate process. I also need to be able to input CJK characters. If I have the
process running as a popup window (WS_POPUP | WS_VISIBLE), all is fine. But if I
have it as a child window (WS_CHILD), the input from XIM is not shown in the
text area. The log file shows that ImmGetCompositionString is always returning 0
even if I have some input in XIM. I am attaching a test program to demonstrate
the bug.
