Yes, but that's the issue/problem.  In Page Setup it says I'm using A4
paper which is 21cm x 29.7cm but the page breaks are marked on my
diagram at 15cm x 24cm.  The margins aren't *that* wide!  :-)

OK, thanks, it wasn't a big problem anyway.

I just happened to move something off the the left (so the top left of
the diagram became (say) -25:0 and wanted a way to get it back to 0:0
when I brought the element back.  I've found that if I exit and restart
dia then it does get back to 0:0.
