XnView Software

Version:
XnView Classic for Windows, 2.49.5

Running on:
Microsoft Windows 10 Professional (x64) Build 19042.867 (20H2)

All .jpg files referenced below are JPEG TrueColor (v1.1), 1920x1080, 24 bits

Folder layout:
* top folder contains (103) .jpg files and (2) sub-folders:
* top\A contains (18) .jpg files
* top\B contains (2) .jpg files

Start XnView from desktop shortcut, browse to the top folder then:
* click menu item Edit, click Select All
* click menu item Create, click Slideshow

After about 2 seconds delay, XnView Classic always crashes.

I can't reproduce, could you post slideshow dialog screenshot? and perhaps image files used

actually duplicate the above set of files and folders on the same rev system;
the crash is 100% reproducible

and slideshow settings?
