XnView Software

Version 0.93 64bits Linux (Comments not saved in *.pgm)

XnView: MP 0.93 - 64 bit
OS: Linux 64bit (Mint Cinnamon 19.1)

In *.pgm files the comment is not saved!
If i open a *.pgm with comment the comment is visible in teh editbox. But when i enter a new comment and save the file it is gone.

To reproduce:
1. Open a *.pgm file and edit comment (Ctrl+D) (Embedded)
2. Hit "Save"
3. Enter the comment edit box again (CTRL+D)
4. The comment is lost!

Actual behaviour (bug): Comments in *.pgm is not stored

Expected behaviour: comments should be stored in *.pgm files

Here is a sample file with embedded comment "C0":
https://www.dropbox.com/s/75jqrfcu604p1 ... 0.pgm?dl=0

currently embedded comment can only be edited for JPEG (lossless)

Pleas change that behavior.
Is a bug because it is possible to edit the comment in xnview. But it does not get saved to the file!
