Unfortunately, the new documentation
has disappeared in the recent cleanup. Douwe and I am going to write new documentation
on github instead, but this will take a while.

Hm I guess you have some preferences left over from v1, or something, or you closed something before. It's not what I mean.
The PPI window is a separate windows showing radar only, but in your case it's apparently hidden. Try right mouse (context menu) on the chart and click "Radar control...". This should bring up a "Radar" dialog with just some buttons. This is called the "radar control menu". It should have as the 2nd button a "Show window" button. Hit that. Now you should get a small radar only window. This is called the "Radar PPI window". It has a "Menu" area at the top right. If you close the control menu you can click that to get the control menu back.
If you leave OpenCPN
it should now store the layout you have and come back up the same way.
