I am seeing an issue in the control website with both Chrome 71.0.3578.98 and Firefox 64.0.2 (64-bit) but it has been happening for a few months now. The issue is that if you accidentally click in the grey space between commands and notes then the window becomes unusable until you refresh the website. This is very annoying. It seems that the button is not properly defined because it is not possible to click on the grey space between any other button.
Then this happens, notice the right side of the display is horribly messed up.
