OS: Windows 10 - 64bit
When unchecking "Auto play (videos)" in settings and then selecting a video in the browser, the video is shown and not played but the slider indicating the position moves.
Effect: Irritating user interface
To reproduce:
1. Uncheck "Auto play (videos)" in Settings: View | View and confirm
2. In XnView browser browse a folder with videos
3. Select the first video in the folder.
Actual behaviour (bug): Video is shown in the preview and not played. Video slider moves as if the video is played.

Expected behaviour: Video is shown in the preview and not played. Video slider does not move.
EDIT: I just realize that this problem occurs with one specific video, only. This specific video drop.avi can be downloaded here: http://www.engr.colostate.edu/me/facil/ ... s/avis.htm
