				 Buttons missing in Sigil 
 
			
			Hi, I've only just started to use Sigil, Yesterday it worked fine. Today I started a new project and realised that there are buttons missing.Both the Validation and Make EPUB buttons are missing and the Metadata pop up looks strange, so that I can't use it.
 
 Any ideas what I've done? or do I have a bad copy?
