XnView Software

I read previous reports about videos and folders showing in full screen, I have them too. But my problem is, I can not go back. I tried deleting XnViewMP folders in Program Files and Roaming and then unpacking some older versions of the program. I went back all the way to 1.3.0, I even tried 32bit ...

XnView MP crashes when I save or download videos in other programs.

Example 1:
In XnView MP I display the Desktop folder
I start downloading a MP4 video in Firefox to Desktop folder (I use Keep2Share)
XnView PM crashes
If I restart XnView PM it crashes again
If I restart XnView PM when the download ...

Thanx for HDPI scaling, looks good on my laptop with HD resolution and Windows 10 with 125% scaling. Everything is fine except the big green Up icon and Search icon in Filelist toolbar. They look too rough and edgy. See picture.

I dont have the sequence, and I am really not in a mood for another reinstall. I give you screenshots of my settings and preffered program view. As soon as I refresh view (F5) or change folder, thumbnails are back and everything is fine.
Don't be confused by Croatian Windows. I currently use ACDSee ...

Just tried fresh install of Windows 10 and 0.75 beta. No change. The first time I start the program it is OK, but when I start changing options, thumbnails are gone.
Dont know which options, I did not try them one by one.
I wish there was a reset to default option.

Lets say it happens in 90% of cases. Somethimes thumbnails on folders are shown but thumbnails on files are not.
I tried new drivers without effect.
I tried different thumbnail compression but no change.
Windows 10 are fresh install.

When I start the program in Windows 10, I get large icons instead of thumbnails. If I refresh view or change folder thumbnails are back. It worked fine under Windows 7.
