I use Windows 10.
So, I opened up in VMWare a Windows 11 copy I have, and copied XYplorer portable there.
Sure enough it had the same behavior, so I ruled out the OS.
Next, tried /fresh and it worked OK, also in Windows 10. It was a settings problem.
Well, that was easy. I started hunting for the culprit in settings, and sure enough I found it.
It was in Usability>Highlight Hovered Items.
If this is off, the arrows do not work.
And since I don't want to enable it, I'll wait for this to change in the future.
This is not the feature I was after, anyway.
What I wanted is an easy way to compare consecutive images, and the hover box flashes and jumps all over, so it won't do.
What I use now is the F11 preview, but it needs to leave the mouse and press the F11 every time, and this is too much if you want it for hundreds of images.
The MDBU was easier to open (right click) but there is no way to scroll through the images (to compare the current image with the next), so no luck there too.
I'll have to keep using IrfanView (just double click and wheel scroll).
It also has an option to make its window dimensions the same with the image (but only if smaller than the screen).
F11 can do that, but only for the bigger side..
Anyway, enough with my rant, mission accomplished!..
