XnView Software

OK, I have now worked out what is going on..

On Classic, there were no options in Settings to change the mouse buttons - on a slide show left and right buttons forward and reverse the slides

On MP, the new mouse settings only apply when browsing a folder of files. They have no effect on a slide ...

Thanks

If there is, I cannot find it.....

Classic screen show uses left and right clicks to move forward and backward through the file.s

MP only goes forward, whichever button is clicked. This seems to have been the case since launch. Limitation or bug?
