There is some explanation of the butterfly window larch issues by a TM member 'twotribes' under the Fabulous Aeromax thread.
To quote him:
Not just open Andy - the butterfly windows have been known to fly off altogether at speed!
For this reason, the factory fit a set of extended studs and use a different window/hinge bonding agent if any Aeromaxes pass through for a factory service. By the time I sold my car, I was on my third set of window glasses, the second (rebonded at a factory service) set having shattered as my Son opened them on a scorching hot day. The Factory was very helpful, accepting that the hinge bond was hard to get right - too flexible and it allows enough play for the windows to fly open, and if too inflexible it doesn't allow for thermal expansion of the glass and it shatters - and fitted a third set which were fine, though the studs fixing the glass do slightly spoil the smooth lines.
