Amaya 9.0pre WinXP bug: "File > Change the document type" does not work

Hi,

In Amaya 9.0 pre for WinXP, it seems that the document doctype can be
changed using the File > Change the document type menu (if the source code
view is opened, the change can be seen in it), but when the document is
saved, the document type remains unchanged.

Best regards,
