I never had the chance to lie to Sir Patrick... I never saw ANY dialog about the breastplate... It was probably just a bug that had to do with other quests I had unfinished somehow... I understand the directx 9 thing.. However a year or 2 after Baldur's Gate came out, Directx 8 messed up the game.. and so they issued a patch to fix it.. Shouldn't be a hard patch to implement...
