When I open a project, or use 'Run' on the homepage, the window that opens has a wide white space below the header, and only 3cm for the three panels below that are used for coding and viewing the output. I cannot adjust the view to make it useable.
This happened first using Chrome, but now using Edge. It happens whether or not I am logged in. I have also tried clearing the cache.
See screenshot below.

I'm not aware of doing anything on the browsers to change the view!
TIA Kathryn
