Cannot escape full screen mode

[reg]

Hi

Whoops.  Thought I would be clever and install TeamViewer on my pc and android tablet. This was the intention to view Radarbox on the tablet.  Worked just fine until I wanted to exit full screen mode. Obviously no escape key on the tablet keyboard. Thought the best thing was to terminate the session with TeamViewer and return to the pc. I then tried the escape key on the pc keyboard. No joy. I have closed down the Airnav program and then restarted it. Just opens with full screen mode and still not able to return to normal screen with the escape key.  Last resort.  Shutting down the pc and restarting.  Still the same result.  any help would be gratefully received.
Thanks

An update. The map is taking up the whole screen, but I do have the toolbar at the top of the screen. Have tried various options from the toolbar but makes no difference to screen size.

Okay.  Panic over. Not sure how I did it but screen is back to normal.
