           Summary: since 0_9_18 edit fields are cleared when clicking in
                    them
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-richedit
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: mteske at imagnos.com


This is happening with "Action Request System" (ARS) software by Remedy,
unfortunately not free. 
When clicking into a text field which already has text in it, the text is cleared.  
Through trying several versions of riched20.dll, I found out that this happened
between 0_9_17 and 0_9_18. The problem is in the WM_SETFONT-handling. 
With trial-and-error I found that there the
    if (bRepaint)
      ME_UpdateRepaint(editor);
causes the problem. If I replace it with 
    if (bRepaint) {
      /*ME_SendOldNotify(editor, EN_CHANGE);*/
      ME_Repaint(editor);
      ME_SendOldNotify(editor, EN_UPDATE);
      ME_SendSelChange(editor);
    }
everything works, so ME_SendOldNotify(editor, EN_CHANGE); seems to cause the
problem. Unfortunately I couldn't find what that does yet...

Let me know if you need any traces.
