Why the focus can get stuck on the taskbar items?

It looks as if I hold the mouse over one of the programs on the panel so the button illuminates. Neither the closure of programmes, nor their folding-unfolding does not help, is treated only by reboot.

Maybe there are more humane ways?

The usual glitch. Easier to restart explorer.exe.
Familiar. Quite often this happens, but I keep forgetting to pay attention to the SW case. So I have to do reboot. Next time will try to kill the Explorer :) thanks! - eliezer_Runolfsson68 commented on October 8th 19 at 01:58

Obviously some kind of glitch. The causes are unknown, but experimentally has been found a relatively simple method of treatment.
It is sufficient to invoke the popup preview window (in the difficulty), and then click the right mouse button on the edge of the window.
