[BRLTTY] On 40-cel display next-window moves 80 characters

[Henk Abma]

Hello,


the subject already tells most of the story:


I have a Focus 40 blue (40 cells). When I start brltty with -v, it 
correctly tells me  I have one row with 40 characters, however, it acts 
like an 80-character display, that is, text to the right of cell 40 
isn't scrolled to and when I press the next-window key, I move 80 
characters in sted of 40.


This is on Ubuntu 16.04, fully updated and Brltty version 5.3.1. I know 
there is a 5.4 available, however I saw nothing in the change log to 
warrant an attempt to try it for this issue.


Any help would be greatly appreciated.


Kind regards,


Henk.
