I made the experience that copying text with tabs to a fill-the-blanks-question leads to problems, e.g. it is not possible any more to select the text for the blanks. As a quick workaround I now copy the text to notepad++ first, remove all the tabs and then copy the cleaned text to AP. This works, however handling text with formatting could be something to improve in AP (e.g. option to paste as text only or an option to remove all formatting).
