I used htop to kill deluge but I kept looking and found LOTS of instances of deluge STILL running!

Thanks for the error report

You would need to use "pkill -9 deluge-gtk" to terminate a non-responding process.
Without that 9 signal the kill command defaults to SIGTERM which is the same as trying to close the window, i.e. asking for a graceful terminate.
