Somewhat off-topic, but I remember Word for Windows 6.0 would take considerable time (like a minute for a 10 page document on my AM386DX/40) to reflow paragraphs across page-breaks (trying to handle widows, orphans &c). If I made an edit to the first page and hit print before it was done, I would end up with a printed document that contained either duplicated or dropped lines at page boundaries.
