Delphi 6 test application

Sometimes I work on linux using our special Delphi (6) applications from 1.1.3
the Wine is unuseable for me because of this.

I attach a sample application, I hope that it helps to fix this. It would be
very important for me, thanks.

Sorry for the bad english, I repeat the bug description:

Sometimes I work on linux using our special Delphi (6) applications. From 1.1.3
the Wine is unuseable for me because of this bug. After desktop switching the
application disappears. This also happens sometimes after minimizing.

I attach a sample application, I hope that it helps to fix this. It would be
very important for me, thanks.

Did this work in an older version of wine?

See bug 15069. That regression affected Delphi's top level window and many
different symptoms depending on the program(version of delphi). Comment 2
implies it worked per 1.1.3 which is about the version I use for my delphi
programs.

I have the same problem with an delphi application. To be more exactly the apps
does not really disappear but is in iconic mode on the virtual desktop I
switched to (I have kwin as windowsmanager).

I found that the following commit is the problem:

8d77c375b27adc490d24d7593769f4e149d4102c

Changing the line in handle_wm_state_notify()

SendMessageW( data->hwnd, WM_SYSCOMMAND, SC_MINIMIZE, 0 );

back to

ShowWindow( data->hwnd, SW_MINIMIZE );

makes the problem disappear.

I made a trace with unchanged 1.1.9 for the delphi application and for notepad
and they behave different. With the delphi applications different hooks are
called before

0025:Call window proc 0x350f39
(hwnd=0x10046,msg=WM_SYSCOMMAND,wp=0000f020,lp=00000000)

appears (with notepad this comes immediately), further there are a lot of hooks
calls between

0025:Call window proc 0x350f39
(hwnd=0x10046,msg=WM_SYSCOMMAND,wp=0000f020,lp=00000000)

and

0025:Ret  window proc 0x350f39
(hwnd=0x10046,msg=WM_SYSCOMMAND,wp=0000f020,lp=00000000) retval=00000000

I think that this is some sort of a race. The window manager has already
switched to the other desktop when the application finally minimizes it's
window.
