Yes, definitly I am sure I use Yed (Version 3.21.1 ) .
I use Windows 11 too.
I first click on file.
Then I click on export.
Then the only offered choice is file format( html or bmp...or pdf or......)
I have then to define a file name
The next proposal is to register the file.
And.......... then I just discovered that at that time I can choose various settings.
So I know understand that it is at this last step that it is prosed to make various adjustments.
So finally everyithing is ok..
I just have to thank you for your help and to say that yed is really an efficient software.
