--- Comment #1 from paulo i30817@gmail.com 2011-09-08 11:48:39 CDT --- Update, it also crashes when you move the ingame viewport towards the left screen edge (only testes with the left edge and top - top didn't crash).
Curiously, the inn area right at the start of the Baldur's gate 1 part of the trilogy mod displays correctly.
