Hi there. Hope someone can advise, a strange problem.

I have a number of Word docs, which are frequently emailed to me. When I open them on my copy of Word 2016, they are absolutely fine. When my boss opens them on his copy of Word 2010 he gets issues.

The documents are created with the Normal style defined as Arial 11pt but when my boss opens the file, it jumps to Arial 12pt.

His Normal template is defined at size 11pt so I have no idea why the font changes. Not only that, if he changes the Normal style back to 11pt, when he saves it as a .pdf it jumps back to size 12. It is sending him crackers and as the resident "expert" (ha ha ) I am the one expected to fix it.

I have no idea what is causing this. The document template is not set up to automatically update. I have deleted his normal template in Windows. I just can't figure out why this keeps changing.

All suggestions, gratefully received.
