Pushing Left + Right Arrow Keys in the Resource List makes the resources disappear / hide. (Collapse and Expand?) Video of Problem: http://screencast.com/t/kqtdXxm0Q
This is similar to double clicking on the "RESOURCES" header. The parent element (RESOURCES) is collapsing. We need to teach TreeOutline not to collapse in these cases or add a flag it honors.
I believe this issue is resolved now, right?
