Basecamp viewed on screen

Hello everyone. Can you tell me why the grid lines on the maps on my screen in Basecamp now appear slanting? - my maps seem to have gone skew-wiff! . Thanks.

It is documented under BaseCamp FAQ14 at https://www.gpsrchive.com/BaseCamp/index.htm. I had to try various combinations with Shift, Ctrl, Alt and Fn before finding out that I needed to use Fn on my Dell laptop!

Alt + Home and Alt + Page Up is the same as the key function without the Alt i.e.they shift the page left or up but do not rotate it!
