Thank you Bruce for all the preious answers. Appreciate it. 

I drew fib retracements on the chart but unbale to remove this drawing. I tried to right click on it but got no response. Thank you. 

When you hover your mouse over the drawing tool on the screen, try to find the squares in the drawing tool. That is where you can actually interect with the drawing tool. You should be able to right-click and select delete using those squares. The rest of the drawing tool isn't clickable.
