Thanks for the post below Martin. On ferreting around in my Windows based Adobe and Foxit applications, I find that they also have "Restore last view settings when reopening documents", which I am embarrassed not to have found before now. So old 'non-locking' Foxit Reader versions become (for me) the best compromise. * No crashes when Therion compiles * Opens pdf to previous page and zoom setting with a four key 'no brainer' sequence * Best overall rendering and opens all but files of 100's MB in size. If Evince could sort out the slow file loading and area rendering errors, then it would be the winner.

It is very useful to find file by preview. Preview (default MacOSX application) - automatically refresh, preserve zoom, but not exact position of view. Acrobat Pro (full) - lock files, there is feature to one-click refresh file if only one file is opened. You may switch on in preferences "Restore last view settings when reopening documents". Acrobat Reader - lock files, there is feature to one-click refresh file if only one file is opened. You may switch on in preferences "Restore last view settings when reopening documents". There are dozens of commercial PDF editors in App Store, but I never tried them.
