For example, I use Foxit for looking at PDFs. Maddeningly, I cannot view two PDFs at the same time in different windows. There is no technical reason for this limitation, in fact, the limitation was deliberately programmed into it.
I'm pretty sure the people who program PDF readers have never actually used them. (There are a number of bizarre and trivial limitations to them that are trivially fixed. For example, many readers can only remember the last page read for the most recently read PDF. So if you open another PDF, your earlier place vanishes.)
