If it's not too private I'll be happy to look at the XML and see what's been done (if anything). john ATSIGN pptalchemy.co.uk
If shapes have somehow opened in read only (not normally possible) then you won't be able to delete them.
If the XML has been altered and you can see "screws" then usually you can cut and paste it (this won't unlock it though)
I've attached an example of an XML'd file
