           Summary: RichEdit: Wrong behaviour when formating an empty
                    selection
           Product: Wine
           Version: 1.1.37
          Platform: x86
               URL: http://www.teamviewer.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: richedit
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: caliga at arcor.de


In our Software TeamViewer, a Richedit control is used to display chat
messages.
The nick names are colored green or blue, the text should remain black.
This works in general...
But if one side sends several chat messages in row, the nick name is omitted
(by TeamViewer).
And then, an empty selection (where the nickname would be) is formated green or
blue.
It seems, that if this happens the second time, something is screwed up and the
color becomes the default color...

Of course TeamViewer could just NOT format the empty selection with
EM_SETCHARFORMAT, (and this will be done in an upcoming release), but still
this is a wine bug, I think.

To reproduce, start a remote support session in TeamViewer from your Linux-box
to a different TeamViewer, then click on Audio/Video/Chat and type three or
more messages.
