I can show an app affected by this bug.

Lunascape Web Browser
http://www.lunascape.tv/

A child window of an MDI client window is not always an MDI child window.
(e.g.: background-image static child window of the client area)

It should not be tiled or cascaded.

if ((GetWindowLongW( win_array[i], GWL_EXSTYLE ) & WS_EX_MDICHILD) !=
WS_EX_MDICHILD) continue;

A child window that is not an MDI window is also moved and resized.
As a result, the MDI child windows are tiled with the wrong size.

In case of Native Windows, it works properly.

That is not difficult.
Looking at the changed size of the window, it is clear.

Also, regardless of that application, the source is not right.

All MDI child windows must be with WS_EX_MDICHILD style.

Do you understand?

More details please, so far this bug looks more like a speculation.

--- Comment #12 from [e-mail]  2010-04-17 06:33:00 ---
In MS Windows, All MDI child windows must be created with the WS_EX_MDICHILD
style.

The CreateMDIWindow API and the WM_MDICREATE message set that style on the
child window automatically.

(The application can use the CreateWindowEx API with the WS_EX_MDICHILD style
to create MDI child windows.)

So, if a child window of an MDI client(parent) window is not with the
WS_EX_MDICHILD style, it is not considered as an MDI child window.

Do you understand?

I've attached a simple test project.

Build it,
run it on Wine,
open a few MDI child windows,
select menu [Window]->[Tile],
and you will see the bug. (blank in the client area)

There's a test application. Unfortunately it doesn't include a binary, and
winemaker can't handle it, since we don't have afxwin.h:

make[1]: Entering directory `/home/austin/MdiTest/MdiTest'
wineg++ -c  -mno-cygwin -I.    -o ChildFrm.o ChildFrm.cpp

Unfortunately the Express versions of Visual Studio will not be able to compile
this (afxwin.h is not available), can anyone help compiling this?

Here is a not MFC based test application, it should be much simpler
to play with. This application shows same behaviour under Windows7 and Wine,
which doesn't confirm this bug report.

I see that your compiled application will not run in XP or lower, so I
recompiled it in Vistual C++ 6. But all I see is a large gray window, no childs
inside. Since the bug has no screenshots can you tell me what is supposed to
happen?

Create some child/MDI windows either using File menu or hotkeys: Ctlr+N
creates child window with WS_EX_MDICHILD style set, Ctrl+C creates child
window without that style. Then either press Ctrl+T or menu Window -> Tile
to tile created windows.

Ok, I see now that when I run in XP the operation
client_cs.hWindowMenu = GetSubMenu(GetMenu(hwnd), 1);
fails so there is no menu and the shortcuts do not work.

According to Dmitry's test this bug is invalid as Wine, Windows 98, XP and 8.1
results in the same tile disposition.
