Hello,
The issue only exist on XP systems, on Windows 7 systems and up, the issue doesn't occur.
This JPEG file is an exception, nearly all JPEG files are previewed correctly.
I have joined the JPEG file to this post as an attachment.

Interesting case. Could not repro it (no XP handy), but it will be handled with more grace in the next beta.
PS: I assume you got the same error when previewing the image in the preview tab?

It's the first time I have an issue like this since 2011 (date of purchasing of my licence).
The file comes from this web page :

In addition to the error, the file is locked by XYplorer once the error is displayed.
I need to close and restart XYplorer for moving or deleting the file.
Regards

This should be fixed as well in the next beta.

In case it may help admin, as I also got XP, I tested that particular pic. Here is the exact moment where it happened :
Code: Select all
15.70.0100 (02-Sep-2015) : decode ok (downloaded from Freezer, tested, also tested some preceding versions, all ok)
====================================
https://www.xyplorer.com/xyfc/viewtopic.php?t=4&start=3407
v15.70.0121 - 2015-09-15 20:39
! Image Preview: Hang on certain corrupt JPGs. Fixed.
v15.70.0124 - 2015-09-18 15:14
! MDBU: Hang on certain corrupt JPGs. Fixed.
! Thumbnails Creation: Hang on certain corrupt JPGs. Fixed.
v15.70.0131 - 2015-09-21 16:45
! Thumbnails Creation: Too many "Can't decode" since v15.70.0124. Fixed.
v15.70.0132 - 2015-09-22 09:32
! Image Preview: Some JPGs were not correctly parsed. Fixed.
15.80.0200 (26-Oct-2015) : doesn't decode (downloaded and tested, also tested some following versions, no decode)
=========================================
It happens same to me, very (very) rarely, that a .jpg doesn't decode on my XP system with the version I use (19.70.0100) but it's not a problem as it happens maximum a couple of times... per year.

pixelsearch gave me an idea.
I did a test with XYplorer 13.90.0100.
Something seems to have been broken.

Indeed.

Should be fixed in the next beta.

No debug build ?
No virtual machine ?

Not worth the pain. This is one malformed JPEG that fails in one outdated OS.
