I can. I seem to remember in System 7's (!) day, where words were hanging 
beyond the margin
of justified paragraphs at low res (e.g. page-preview?) . i.e. the screen 
output was indeed different from printed output.

I haven't done any major document-writing activities on the Mac since those 
days :-).

Yes, that's the first line in CalcDevMetrics() :-) :
