If you care to help us out, you may test out the patch we are planning to release at your own risk. That patch should fix all your problems.
http://www.larian.com/dragonknightsaga_support_forum.phpBy "at your own risk" I simply mean: not everything may work as it should, as some resolution issues were reported. It's not like your computer will explode or your savegames will be unusable, that is not the case

Note: the bugs will only be fixed when you start a new game. Your current savegames already contain the bug. If you want the savegames to be fixed and not restart, you may send your latest savegame to support at larian dot com
