First off, I'm running Windows 7 and I'm running the game at 1366x768.
When I enter a dialogue tree, my cursor seems to be out of line with the options. It appears lower than the actual line that is selected. Also, it appears as the normal windows cursor, don't know if that's deliberate or not.
This could be all related to another problem I've been experiencing which crops up if I move the cursor to the edge of the screen. It turns back into the windows cursor and won't move unless I pull it away from the edge of the screen. It's a minor annoyance at most but it seemed like it might be related.
EDIT: Wrong section
