Yes, it kept happening after I closed and oppened the game again. It just happens anywhere on the game, including the start menu an the storyline. Things get selected when the cursor is hovering over them, and text keeps advancing.
I've been thinking about it, and i think this may be due to my x-box style gamepad. The right trigger has a mind of its own and it activates randomly, so if the game has compatibility with gamepad, the issue may be just mine.
