File export does not work after image joining - V0.79

[masterjp]

I often create a picture collage e.g. of 4 pictures.
In the file browser I select 4 jpeg files.

I go to the menue: Create => join images

XN-View MP creates a correct collage of the selected files and name the picture "<empty>".

Then I want to export the picture file.

Menue: File => Export...

Nothing happend!

I think XN-View MP can not export it, because the new created picture has no name.
If I import a picture from clipboard it will get a new name "clipboard" and Number.

"export" must no be available, you need to use save

Export (File » Export) is available after joining images or after making a screenshot in v0.84.
