Hi Robbo,

I replied to you last week but it never got uploaded to the forum.

“It’s seems to be a bit of a unique bug! Thanks for Replying 🙂
I do think it is something to do with the calibration as it is harder to calibrate in those areas and stops tracking well (during calibration), but the topography generation is fine in those areas.

If I run ‘bin/SARndbox -h’ in the terminal it runs the program with a black and white moveable topographic map but no options.
I’ve tried -wts before unfortunately and found that it only changed the resolution, not the area effected.”

I have however found a fix for this problem. I had to change the co-ordinates in the Boxlayout textfile and set it larger than was needed for the topography. I also changed the values so there are only 5 numbers, Left, Right, Top, Bottom & Depth
So the file reads Top line then (Left, Bottom, Depth) (Right, Bottom, Depth) (Left, Top, Depth) (Right, Top, Depth).

This fixed the issue even before re-calibrating. When opening the calibration before only a section of the screen flashed red on start up while now the whole screen flashes red (When refreshing the screen the whole screen has always turned red)
