When I click on Plasma Lock/Logout widget on panel first time, it normally displays popup window with Yes/No buttons. But if I click outside of it (in other window) this popup windows goes to background and very often becomes hidden by full-screen window. After this second and all following does nothing for user, because widget think that it already show window. Only when I minimize all windows manually, I can see Lock/Logout widget window and operate with it. Solution for this problem can be force hide and show popup window, or force move it at first layer above all other windows.
which button did you click? Suspend?
I don't click any button in widget, very often I do missclick outside widget popup window, after this all other clicks on widget button does nothing.
Button is yes, Suspend.
I retest Lock/Logout widget with Lock and Switch buttons, but they don't show the confirmation popup (Yes/No) window, so the problem is not reproduced with them. But will be good to have option for enable confirmation on those actions too, like in Suspend.
Thanks for confirming that the originally reported issue is no longer happening. :)
