Person A generates a document, using Power Point (don’t ask). Sends it to person B. The document displays slightly differently on person’s B computer, due to differences in fonts, environment, program version. B performs minor changes to “fix” these displays differences, and sends the document back to A. A then see differences in his own computer, fix them, and sends them back to B.
Rinse, Repeat.

One is using Microsoft Office and the other uses Libre Office, isn’t it?! :-)
