On my Bullet, the emergency windows are hinged at the top and held in place at the bottom by a support bar that you first unlatch, swing 90 degrees towards you, and then push outward to open up, locking in place using a red plastic tab. Is this the kind of window you have? If so, which "latches" have come loose? Can you post a photo?
My emergency windows are designed poorly, and I hope I never have to use them. The hinged support bar and plastic tabs are flimsy, and have jarred loose during transit a few times already (during which the window can be subject to flapping due to buffeting winds). I constantly have to make sure they are firmly locked in place before I tow.
