When I'm checking all accessible child elements (XAccessible) of an XAccessibleContext (var c = haystack.getAccessibleChild(i);) via the cli api from C# the api seems to fall into some kind of dead lock. The OpenOffice process stops and doesn't response for any user interaction. When I abort my requesting application OpenOffice runs normally from this point.

I'm checking every available XShape on an XDrawPage for its XAccessible counterpart in parallel, starting the search from the base XAccessible which I have received from the XDrawPagesObservers Model ComponentWindow. Testing all elements serial will take too much time. The time until it hangs on isn't every time the same. I don't found any rule when it starts hanging.

In my testes I have a draw doc width circa 30 objects, building (incl. bézier curves for text) nearly 100 objects in the navigation tree.
