650 - Focus resize bug

[Dreamer]

- use clean, default settings
- use NC mode
- create small window
- follow the steps on the video
- if the window is not re-sized, the file in second column is focused correctly
- resize the window width
= selection of the file in second column is incorrect

Fixed in 652, thanks Marek. (Needs more testing though, still testing...)
