Notation Composer and Musician 251 maintenance release

Hi Mark,
re the PDF printing problem, I have gone back to V2.2 (yet again). Just doing an install and re-install didn't work, but I had to do a system restore. Fortunately, because of the problems I have with Composer updates, I now do a system checkpoint before trying out new releases.

As far as I'm concerned PDF printing with PDF955 works under V2.2, and therefore should also work with V2.5.2.

I don't plan to install any more Composer 'updates', as I find it just too frustrating,and stressful, and the bug fixes don't usually apply to my areas of concern (which you indicated are very low priority, even though they annoy me every day). I'll leave it to others to 'debug' your software.
