Bug 413624

SUMMARY
If I click on "Leave..." I got a black screen with some options (one of them checked) and two buttons, "OK" and "Cancel":

1. if I click on "OK" I came back to Plasma and my system will shut down (or it will reboot, or something else);
2. if I click on "Cancel" I came back to Plasma and I can continue my work;
3. if I click elsewhere (I mean, not on a button) I came back to Plasma and nothing happens.

I think the latter is tricky, because it's the same than 2. but I have no feedback on what will happen. I mean, I can't be sure if I hitted the "OK" button or I clicked "near" it (ok, maybe I'm getting old...), so my system will shut down or not?

STEPS TO REPRODUCE
1. Click on "Leave..." or on "Reboot..." or on "Switch User..."
2. Click on the "Cancel" button
3. Repeat step 1. but now click elsewhere (not on a button): the results are the same.

OBSERVED RESULT
In this moment we don't need a "Cancel" button, since its result is the same than clicking elsewhere.

EXPECTED RESULT
I think the shutting down process should be cancelled only by clicking the proper button, and maybe I should have a visual feedback, too.
