[RESOLVED]SONG TEXT DISPLAYS IN BOTTOM CORNER

We're new to EW6, having used 2009 for a number of years. I'm trying to get the song text to display on the Live screen across the whole of the background image, but it displays towards the bottom left hand corner. Any ideas, please?

To add a bit more. I want the default slide format to position the text box centrally on the background with the text filling that text box. I can manipulate slides individually in the 'Inspector' bit to enlarge the text box size and the font size, but that is far too cumbersome and I want to set a new default.

SORTED! I was using a theme for the songs which had the words text box in the bottom left hand side. I have now created my own themes, using the same images, and made the text box the same size as the screen, brought the text box to the front and all is well.
