Narrative:
It was my takeoff. On takeoff roll just after the 80 KTS call I heard increasing wind noise coming from the copilot sliding window. I notified captain and he noticed that the latching handle was not in the stowed position; even though the window appeared closed. He took aircraft control and performed a rejected takeoff at approximately 90-95 KTS. We referenced the brake cooling charts and contacted maintenance; operations; and dispatch. During the before starting engines checklist the handle was physically checked by myself and crosschecked by the captain. The only thing I can come up with is that on taxi my headset cord became looped over the latching handle. I slid the cord back over the handle and may have inadvertently tapped the top of the handle and unlocked it. The handle must have slowly opened unnoticed during taxi and takeoff roll. In my opinion the button that is depressed on top of the handle seems very sensitive.
