sometimes when I launch the game once I'm at the main menu the mouse cursor is off-set compared to the option being highlighted. (it happens 50% of the time),

concret example : if my mouse cursor is pointing on "play" the highlighted line is "credits". and if i click on "play" it's the "credits" that is opened.

when the bug occurs it's always 4 lines offset to the bottom, and also impact all the sub menus.

the only way to fix it is to restart the game.

I tried to take a video with fraps but surprisingly the bug doesn't show up when i play the video (while the bug was really here during the recording).
