Yes I too have this problem. Also, when I press and move the marker line (press and hold left mouse), the marker line is not moving. But when I release the mouse, the marker line jumps many bars which means internally the line is moving and not seen visibly. If I move the marker line bar by bar, it is moving. When I move the marker line, the CPU usage goes up from 0% to 60%. I use one symbol in 3 sheets (1st sheet 30 minutes time frame, 2nd 5minutes time frame and 3rd sheet 1 minute time frame) and all the 3 sheets are "symbol linked". I use version 5.10.
