[Bug 11951] New: Tide prediction cursor popup or tag creates " Untitled Window"

http://bugs.winehq.org/show_bug.cgi?id=11951

Summary: Tide prediction cursor popup or tag creates "Untitled
                    Window"
           Product: Wine
           Version: 0.9.57.
          Platform: PC
               URL: http://wxtide32.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

WXTide32 includes a feature to show tide data by creating a cursor that tracks
time of day and water height.  It appears when the main window is opened and
showing the realtime, graph, or overview display, and the user presses either
the left-arrow or right-arrow key.  A popup or tag follows the vertical part of
the cursor line, showing the data for the time (vertical cursor line) and depth
or height of water (horizontal cursor line).

Under Wine, the cursor lines are drawn but the cursor popup or tag is missing
or flashes briefly (hard to tell which is happening).  At the same time, a new
entry appears in the task bar: "Untitled Window".  The app then blinks between
idle (based on the regular movable cursor, controlled by a mouse, etc.) and
busy, with "Untitled Window" showing in the task bar while the mouse cursor
signals "busy".  On minimizing the main window (showing the tide levels), the
"Untitled Window" entry remains in the task bar.  It cannot be maximized,
opened, or closed.  Only terminating the application removes "Untitled Window".
 No messages are written to stdout or stderr when the problem occurs.

Under Windows, the key-controlled cursor moves as expected, with a popup
attached to the scrolling cursor.  No additional tasks appear in the task bar.
