1.3.1 - BUG - View-Mode - Save as ... doesn't work

[PeterNC750]

using
XnViewMP: 1.3.1 - 64bit (portable)
OS: Windows 10 - 64bit

To reproduce:
- modify a picture in ViewMode (for example: resize or crop)
- trying to save the modified picture with Save As ... (with toolbar-icon / or menue-item File/Save As... / or hitting ESC -> "Save changed file"-dialog appears with button "Save As..." / or pressing Ctrl-Shift-S)
- it is not possible to save the modified picture under a different filename


Using the older version 1.3.0:
all above mentioned possibilities are working well

it works here, which output format do you use?

[PeterNC750]

in
Settings/Formats/Saving
only JPEG/JFIF is selected.

Maybe my words "Save as ... doesn't work" are mistakable.
It's better to say:
the "Save As - dialog window" doesn't appear

Thanks to your detailed description I can reproduce the problem.

A workaround is to select more than 5 formats in Settings>Formats

[PeterNC750]

Very cool workaround
Now it work's ...
