Document>Line Wrapping is activated
Now there are two new disadvantages: - there is an empty line where I can't even place the cursor (between 15 and 16) - if I navigate on the keyboard with the key arrow-down from line 13 to 16, the cursor will stop at line 15 at the end of the line; even if I press again many times the key arrow-down, the cursor will not move (but navigating with the key arrow-up from line 17 to line 13, then there are no problems)
I think that all the problems are because the line stops at the right border. One reason could be that there is not enough place for the wrapping-symbol on the right side.
