Pasting text which spans more than one page is very difficult to handle as the text which is beyond the bottom of the page, disappears.

So the only way to currently handle this is to :

(a) measure how much text can fit into the page, then

(b) somehow, 'cut' out the text at the bottom which does not fit within the page ( this is not easy to do ).

(c) go to the next page and repeat the above process till all your text is pasted across multiple pages.

A NIGHTMARE.
