multiple select in point hierarchy

Hi,
When I hold CTRL and select multiple points in the point hierarchy page I am able to move the selected points to a folder in one click + drag. The problem is while holding CTRL and clicking the various points to select them I would expect the background colour on each point selected to change, indicating that it has been selected. This does not happen.

Trying to select multiple with SHIFT in IE7 resulted in some strange screen drawing as well, with the inverse of the selection getting a blue background.

Perhaps this is more of a dojo issue than mango?

Not sure, but i'm assuming for now that it is a Dojo thing. It's possible that there's an API fix for this, but the documentation is wanting.
