It is in the DNA - my 07 shows the same - I can verify that it launches inverted and flies inverted - all be it with slower response - has got me to shore on more than one occasion.
Hardly flown it this season as Lithium has replaced it - suppose should sell - but great kite power grunt balance predictable - sigh -
I still have first 2003 kite been threatening my youngster to get it out and see if he can make it perform[}:)][}:)] (allowance is he can use a modern bar!!) - just waiting till he gets a bit heavier as it is a 12M.
However the '07 does not behave so well as U describe at the edge of the window - most kites (especially more delta) are good to sit and wait at the edge of the window - excpt when the wind picks up
