Actually, this should have been obvious to me if I'd been thinking clearly. Doing a "import curses" shouldn't make bare library symbols available in your code. It only makes sense you'd need to address them with a prefix. It may be argued that I shouldn't do the import this way. However, I prefer to have "curses." in front of things imported. It makes the link explicit, and serves to remind me of what's actually going on, when I revisit the code in five years. Paul -- Paul M.
