Hi "Kyowash" and "Catweasel",
Thanks for posting this for those that do not already know this.
FYI-1: My KDE systems have always had a key combination to Kill an unresponsive applications, Ctrl+Alt+Esc. This changes the cursor to the Kill application cursor (Pirate cursor) and you just click on the Titlebar (anywhere in the application window really) of the application you want to stop. If I am not mistaken, all Linux Mint editions can assign a Key combination to do the same thing. Hit ESC to not kill anything...
FYI -2: There are other posts on this in this forum already.
