Suggestion how to handle processes not responding better

[plomari]

The dialog complaining about clients not responding appears too often and and situations when the clients are responding properly. (Example: claws-mail, click Compose, write some text, close editor window, it asks you whether to discard or save the mail, and after a while the icewm dialog pops up for no reason.)

I suggest one or both the following:

• show the dialog only when clicking the window close button a second time and nothing else was clicked
• offer killing the process or the client in the window menu

When you press the close button, icewm sends a ping and a close request. Your client should then either close the window or reply to the ping request. Apparently this client doesn't do that. Annoying, but as long as it is unclear why, i see no reason to change anything. Claws-mail offers to close its compose window either via its menu or via its hotkey Ctrl+W. If you use those, you'll circumvent this case.

It happens with other clients too, though I don't remember which ones exactly. (I can post them when I encounter them again.)

OK, but anything non-reproducable has little value.

BTW, you can already immediately kill a client via the WindowList. Right click over the app.

Your "second time" suggestion is too complicated and non-intuitive and violates POLA.
