Horizontal mouse scrolling problem

[YossiD]

I am unable to scroll horizontally with my mouse wheel in Irfanview. The mouse is a Logitech M510 with left/right scrolling by pushing the mouse wheel to one side or the other. The scrolling works fine in other programs (e.g. Visio, word, Excel, etc.), but not in Irfanview.

Using Irfanview 4.52-64 bit on Win 10/64.

Any advice?

Try using Shift+Scrollwheel.
