Hi Mark,
I reloaded 2.5.1 and also a different free PDF file creator (PDFCreator) to see if the print problem was confined to the particular free PDF program I was using.

I'm pleased to be able to report that on my Vista computer this worked perfectly with Composer 2.5.1, unlike the PDF995 program which seemed to be one print behind.

That is a real relief form me, and so I will continue use 2.5.1, although I see that 2.5.2 maybe out soon. My apologies for expressing some frustration over this problem, and thanks for your patience and suggested test/solution.

Cheers ... Clyde
