When the option "Move the top panel" panel with scrolled moves, but a color strip that indicates the column in which the cursor disappears. It is only when the bar is not displaced. Strip showing the line at this. A feeling that the mark column is there, at the top and when scrolled does not move with the panel. began today, the high yesterday, before that it was fine. It only at me such glitch, or at all?
