Wrong folder marked when going up one level from thumbnail view

[HansSchrauber]

XnView: MP 1.10.5- 64 bit
OS: Windows 64bit

When going one level up from thumbnail view the marker jumps to the first folder instead of marking the folder previously opened.

Effect: focus on file I was working on is lost

To reproduce:
1. create several folders containing pictures
2. open a folder in the middle of that folder
3. go one level up to first folder

Actual behaviour (bug): marker jumps to the first folder

Expected behaviour: marking the folder previously opened

strange.....

when I open a single picture using the windows explorer, it opens and the bug does not occur!!!
