--- Comment #1 from Vincent Povirk madewokherd@gmail.com --- Wine does support _NET_WM_PING, but it can only respond to pings via the application's message loop. This is consistent with the purpose of _NET_WM_PING, and Windows has a similar feature where it can detect unresponsive apps.
On Windows in my testing, if you click on a window that's been unresponsive for about 5 seconds, it will grey out the window and add "(Not Responding)" to the window title. Is it possible to make Windows do this by clicking at the right time in the loading process?
