Summary: HTTRANSPARENT is ignored
           Product: Wine
           Version: 0.9.40.
          Platform: PC
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When user clicks on a window, Windows first sends WM_NCHITTEST and checks the 
result. If the result is HTTRANSPARENT, it sends check first underlying window 
in Z-order that is not HTTRANSPARENT and sends mouse click to it/activates it.
Wine ignores this and click goes to the window that responded with 
HTTRANSPARENT.
It breaks functionality of Tooltip / hint windows that are not supposed to 
handle clicks but route them to the underlying window.
