1.4.5 XnView goes to background after file deletion

[Ceomant]

XnView: MP 1.4.5 64 bit
OS: Windows 10 64bit

Exactly the same bug that is treated in this 2008 (!!!) bug report: https://www.google.com/url?sa=t&rct=j&q ... zXN8lIaYu9

After deleting a file, XnView goes to background. It happens in windowed mode or fullscreen.

I get this, without any major change to XnView nor my OS, after years of use in three computers, at least 2 years in ths one.

Effect: you need to navigate again to XnView.

To reproduce:
1. Open an image in a folder with more images.
2. Delete any image.
3. XnView goes to the next image.
Actual behaviour (bug): XnView goes to background

Expected behaviour: XnView stay active.

After today Windows 10 update, the problem is gone, I hope for good.
