This is a screen shot showing the dialog with the not functioning button
When try to save a document in a new folder this is not possible to be done from the 'Save as' dialogue.
This is because the software button dedicated to create new folder is not functioning.
When I click with the mouse this button it closes the dialogue instead to open a new dialogue to create a new folder.
Please see the attachment.
There I put a red arrow to this button.
This is already fixed for the upcoming 4.3.1 release.
