Video files lead to crashing XnView with scroll wheel

The scroll wheel works great with still image files. When I encounter an .mp4 file, repeated use of the wheel will often lead to a freeze. Also, waiting for the movie to end then scrolling forward will also lead to a freeze. Ctrl-Alt-Del becomes necessary. I have a mix of .jpg and .mp4 files in my directory, with an occasional .gif or .png. While larger .mp4 files tend to cause more problems, I think I could create a crash with any of them. Just scroll back and forth.

The workaround is to navigate with the Next File/Previous file icons in the toolbar. But fixing this scroll wheel bug would still be nice.

Within my current settings, disabling read-ahead doesn't appear to help.

XnView Version: 2.49.3
MS Windows 10 Pro 10.0.18363 Build 18363

(I could only find the xnview.ini file after I checked the About dialog box. Perhaps the 2007 sticky on this forum should be updated.)

Renaming xnview.ini to xnview.bak reminded me that I had changed the scroll wheel setting to "Next file/Previous file". When I changed the clean install to that setting, I was still able to recreate the program freeze/crash. It's possible that "Fit Image to Window" and/or "Sort files by date" makes the problem worse: I'm not certain.
