After generating the flight, the screen locks and the left part as the mouse pointer turns black and does not allow anything else to be done.

Hi, this could be a bug in the Chrome browser. I can’t reproduce it on my end but it could depend on your graphics driver/card combination as well.

Can you try going into the Chrome flags settings, and changing the “ANGLE graphics backend” setting to either “OpenGL” or “D3D9” and see if either of those help? Make sure to restart your browser between changes, otherwise the setting will not be applied.

You can go to the setting directly by pasting this into your Chrome address bar: `chrome://flags/#use-angle`.
