Site title hyphen – can't remove it !

Hi all. I have a liddle hyphen “-” in front of my Sitename in the title of the page. And I can’t find where this mysterious hyphen is coming from. I use the Parabola theme (which is fantastic).

So the site title in the browser should be: [Mysitename]
but instead says[- MySitename]

I have looked in header.php but can’t see anything there. And obviously the “Site title & tagline” text is fine. It has no hyphen. Any idea where this hyphen is coming from ? It’s driving me nuts !
