Version 0.93.1 64bits (Mar 7 2019)
When I'm in single image mode, and I use the Edit IPTC/XMP tool to edit the caption, the value doesn't stick. It holds the value for as long as I'm in single image mode (I can even go onto next image and then return), and I can reopen the dialog and see my changes, but when I go back to Browse mode, I can't see my changes any more if I open the same dialog from Browse Mode. (Interestingly, I *can* see my changes again when I reopen the single image BUT when I close XNVIew MP any changes made in Single Image mode are discarded.)
Effect: IPTC Caption edits are lost - and not in an obvious way.
To reproduce:
1. Double click on an image in Browse mode to Open it
2. Open the Edit IPTC-IIM/XMP dialog, using the Ctrl+I shortcut or via Tool menu
3. Make a change to the Caption text and hit Apply
4. Reopen dialog and verify that change is still there.
4a. Move onto another image and back, verify change
5. Exit to Browse mode and use Tooltip (or Edit IPTC dialog) to see the caption - change is NOT there
6. Reopen the image in single mode and see that change IS there
7. Restart XNView MP and the change is now permanently discarded
Expected behaviour: Editing caption text box from Single Image mode and clicking Apply correctly saves that text into the correct field
I love that I can access the Edit IPTC dialog from Single Image mode - this was a feature that I requested, so thanks for implementing it

Best regards,
Julie
