A student pointed out that the following behavior is probably undesirable:
- student enters answers
- student presses "preview"
- answers are displayed in the answer blanks and previewed
- student presses "current"
- current answers are -not- placed in the answer blanks for
This makes sense, because the answers for the problem page are obtained
from submitted answers in the database, of which there are none until
the student presses "submit." I glanced at the code to processProblem8.pl
to see if a quick work-around leapt out at me (it didn't), and then
thought I'd see what the wisdom of those wiser than I had to suggest in
