Bug ID: 38759
           Summary: WM_USER (and +1, +2) are being sent to application
                    windows
           Product: Wine
           Version: 1.7.38
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

My programs use WM_USER, WM_USER+1 and WM_USER+2 for various functions, but
they seem to be sent these messages by WINE when the mouse moves around the
window involved, possibly during repainting.  This doesn't happen in Windows. 
I've changed my offsets of 0x0400 to add 0x0280 (I now start acting on messages
at 0x0680 instead) and it's fixed - but it's clearly a bug in WINE.
