Narrative:

During takeoff roll the first officer's window popped open. The takeoff was aborted and we returned to the ramp for maintenance. There was no indication of a faulty lock or unsecured window as we had not opened the window that morning and the handle was in the secured position and no noise was noted coming from the window prior to it popping open. The drain tube apparently got caught in the lower corner of the window and prevented a secure lock.
