You could give a clue to anyone else with the same problem! Was it that you needed to toggle the enable in options->editor not to interpret the file header (fills the display pane with the introductory page gumph)?
Naw...At the top of the lower right-hand pane is a Zoom slider control thingy and to the right of that is a page display selector control widjet. You have select the 'up' direction to view the score. I wanted page 2 so I was beating on the 'down' selector button to go 'down' for page 2. Who knew you had to hit 'up' to go 'down'...not documented, not intuitive enough for me.
Ah, but if you toggle the option about file headers, then the output is only one page, so there is no need to click on direction selectors!
Didn't see where that was documented anywhere...I was looking for the 'dummies' section where it decribes each control and it's effect...and so until then I just mash buttons and fat finger controls until it works after a fashion more fun that way.
