Font Size/Para Spacing Changing from one PC to another

I have been developing for two clients in Fance & England for years, and I've never had this problem. I create a program in Lectora for them, and everything looks great. I publish it to HTML for them to test (loaded on the back end of my web site), and it all is good. I send them the Lectora files, and when they open them on their PCs, the fonts are larger and the paragraph spacing increases. Therefore, the text boxes print on top of each other. Some text is just missing. It seems that this started happening after the last maintenance release. We are all on Lectora Inspire vX.6 (8457).

Has anyone seen this probem? Is there a solution?
