I am not really sure how to define this problem, but I will try.
Please feel free to tell me the correct terminology for the items
which I will call by incorrect names.
On the KDE desktop, there is a panel at the bottom of my screen,
similar to what W$ users call 'the task bar'. The widget (I guess)
in the middle of it ('task manager'?) shows currently running programs/windows.
When my mouse hovers over the icon/button of a particular program,
e.g. Firefox, I see popup mini-representations of the windows owned
by that program.
I hope you are still with me... :-)
Now to my question/problem. Until recently, those popup copies of
active windows each had a small 'X' button in the upper right-hand
corner, which I could click to just close that window. I did not need to
actually *activate* the window, by clicking on its representation, and THEN
close it, I could just close it from the popup.
This ability seems to have disappeared, and I find my desktop work slowed down.
I need to either click the window (possibly changing active desktop) and then
close it, and then return to the desktop I am busy in, OR, *click* the task
manager icon to get a different popup, a set of horizontal buttons representing
the different windows, and go through the same rigamarole to close a window.
So... Is there some configuration option somewhere which will return my ability to
quickly and easily close windows from the task manager popups?
