The running screen in Windows

Reproduce:

1, Download the test program from:
http://www.imakevideo.com/set_focus_bug.exe

2, wine set_focus_bug.exe

3, Click the compute name button,
a layered tool window will pop up to show host name.
In Windows the pop up window will keep visible until the user click the mouse
in the main dialog window or switch to other program (see the attache png file)
.

But in Wine the pop up window will be closed immediately when present.
