When I play Puzzle Quest: Challenge of the Warlords, my touch screen doesn't seem to register my stylus movements. Touching works but dragging/swapping jewels doesn't work in a lot of cases and sometimes I even end up swapping the wrong items, wasting a turn. But my touch screen works just fine in The Legend of Zelda: Phantom Hourglass so I don't really think it's my touch screen, just the game's quirkyness. But maybe you can tell me what's wrong with either the game or my touch screen.

Btw, they're both roms, just so you know.
