XEEN: Multiple-choice talk selection display issue

[darkstar]

When talking to some NPCs, you get a menu on the right side screen with up to 3 possible answers (1, 2 or 3)

That display is often a bit broken:

• first, the "1" button seems to have some sort of shadow to the left
• second, in some instances, the regular command buttons are not removed before drawing the buttons

I have attached a screenshot and a savegame (just click on the table to start the conversation)
