I admit the question is kind of stupid, but I honestly can't do anything about this weird issue.
I've added a Clock screenlet (with a custom theme) on my desktop and the thing is that I can't remove it. What I can do is to add another clock, click on it and "Quit all clocks" which removes them from the screen, but I can't remove the first one individually. The problem is that usually you can click on it and it shows the menu. But in this case wherever I click it shows ordinary desktop options, so I can't select it in any way.
How can I do it, maybe there is some way of interacting with them through command line?
