[Bug 13886] New: Focus is killed after unminimizing the window

http://bugs.winehq.org/show_bug.cgi?id=13886

Summary: Focus is killed after unminimizing the window
           Product: Wine
           Version: CVS/GIT
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P4
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Steps to produce the bug:
1. Open up Wine's wordpad
wine wordpad
2. Minimize the window
3. Restore the window
Afterwards the window will have focus but the caret will not be shown.

I tested this on KDE 3.5.9 and Gnome 2.22.2 with the same bug occurring on
both.

I tested wordpad in Windows XP SP3, and there was no issue there.
I tested with WINEDLLOVERRIDES="riched20=n" and the bug occurred.
> From this I believe that it isn't a wordpad, or richedit issue.

I added some MESSAGE statements to find the sequence of events that cause the
cursor not to be shown, and this is what I found.

1. After the window is minimized WM_KILLFOCUS is sent to the richedit control
as expected.
2. After the window is restored, WM_SETFOCUS is sent as expected, then another
WM_KILLFOCUS is incorrectly sent which will cause the caret to be hidden and
destroyed.
