XnView Software

I have folder with 3 EXR files and when i open first file fast press right arrow key (->) to switch to next file program crash.

Had to upload separately because hosting size limitations.
Zip One & Zip Two - create new folder then export all three files there.

Thank you for your problem report and sample EXR files. I've downloaded the two ZIP archives, upacked them, and then tried to reproduce the problem. Viewing the files in XnView is comparatively slow but there was no crash. I even duplicated the three files several times and then tried, again, but without any crash. (XnView MP 1.00 on Windows 10)

Does this crash occur all the time? I suspect that it has something to do with image caching; could you please try and deactivate "Read on image ahead" and "Keep current image" in Tools > Settings | View | Misc.? Deactivating two-pass rendering (on the same page) might be also a good idea.
