Hi there.  I just bought Death Knights of Krynn, but I'm having some problems.
When I try to memorize spells in an inn or anywhere for that matter, I select
the spells, keep them, but when I select "rest" 00:00:00 comes up.  If I
add the required time manually, the spells are not memorized.  In the
process of trial and error, I picked one character, picked the spells, and
the correct rest time popped up.  I rested the required duration, and the
messages "X has memorized spell Y" flew by, but no spells were actually
memorized.  Is this a known bug in this game?  What am I doing wrong?
Yes, I have RTFM, and I have played 5 other SSI AD&D games.  I never had
this problem before.  Posted or e-mailed replies are appreciated.
