Hi Travis,
Thanks a lot for responding to my question.
The Inspect tool follow focus can not get objects of this app mainly because
they are not focusable (one can not tab to them).
Besides, because of a big blanket object which hovers all other objects, the
follow mouse feature of Inspect fails as well.
Due to the above reason, GetObjectAtPoint() would fail to pick up any object
other than the blanket one.
I believe AccExplorer tool is successful in capturing the objects because
it's using the OLEACC AccessibleChildren object enumerator function.
Cheers,
Kamil
