Bug ID: 56104
           Summary: Combobox - list shall not close when a key is pressed
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: comctl32
          Assignee: [e-mail]

Combobox - list shall not close when a key is pressed. It should put selection
to the first entry of the list starting by this letter (then moving to the
next, etc...) but NOT automatically close the list

Fix : in COMBO_WindowProc, if list is dropped (CBF_DROPPED) and a key is
pressed, then the "no roll up" (CBF_NOROLLUP) shall be set

case WM_CHAR:
case WM_IME_CHAR:
        {
            HWND hwndTarget;

/* This is the fix */
            if (lphc->wState & CBF_DROPPED)
                lphc->wState |= CBF_NOROLLUP;
/* End of the fix */

if ( lphc->wState & CBF_EDIT )
                hwndTarget = lphc->hWndEdit;
            else
                hwndTarget = lphc->hWndLBox;
           return SendMessageW(hwndTarget, message, wParam, lParam);
        }
