I am writing in a Word (2010) document on a PC, and I saved my docx document (among other places) into "Drive". I then accessed "Drive" on my Tablet. (There is no Apple involved here, so this is not a question of Mac/Microsoft. The Tablet is a recent Samsung.) I opened the docx document from Drive for proof-reading. However, although the page numbers agree, occasionally the Tablet version inserts spaces between lines that were not in the original document. (I double-checked: there is no page break involved.) As well, it sometimes separated punctuation onto the next line, even though in the original there was no space between word and punctuation so that it should have been read as a single word. I saved the original docx into a pdf document, and these anomalies did not appear. Any idea what is going on here?
