Mistake is happening in a random way (can week enjoy the system and not meet its,and can and for couple of hours several times its see). For example,I open one window,the second ,the third ,then close the first or the second, but the indicators of open Windows do not shift to closed... don't know how to explain it...see screenshot....
the screenshot shows-thunar was opened,it was copying files, then I closed the main window thunar ,and in its place on the panel remained void
