This "random windows popping up" I think must be the tooltips on windows
for newbies. Turn them off via the Help menu.

It wasn't happening with Quick LilyPond Export only with Quick LilyPond
Part. So you would get confused if you ran both scripts with and without
having a filename available for the scripts to export to.
Ok, I just fixed the Quick LilyPond Export silently failing if no file
name exists for the score. The Quick LilyPond Part script did warn about
this already. And the tooltips *do* explain where the output is or whatever.

yes - if you have 20 staffs then it would be worth putting a loop round
the script, I see that I've done this for the conversion of incorrect
slurs to ties (it's in the Notes/Rests->Ties menu in 2.0.0).

Thanks for the background info on fonts, aliasing and hinting. LilyPond
does hinting (I think - different fonts for different point sizes?),
that's why the typesets are so good. Some day a fonts guru will come
across denemo.ttf and make it beautiful...
