I'm working on "Show the Desktop" feature. I found a fatal bug on it.
An owned window is hidden when its owner is minimized.
I made two test programs to investigate this problem. This is it: https://github.com/katahiromz/wintest
1. Execute target.exe.
2. A window with a modal dialog will be started.
3. Read the title bar's window handle value.
4. Execute minimize.exe with the window handle value.
