Uwe, whatever you did, please undo it.
Done.
The default button corresponds to the default action taken on batch exports.
Ah, now I understand why this reintroduced bug 2762.
So, if you made the overwrite button the default, you are reintroducing bug 2762. If you are concerned about the dialog, now there is a new preference in Preferences->Output->General where you can instruct lyx to overwrite files on export from the GUI, so you will not even have to answer any dialog.
Nice feature! regards Uwe
