ToolTips in Layered Layouts

Hi, I have a layout which is layered for various reasons. The basic structure looks like this:

<MyGUI type="Layout>
<Widget type=Canvas name="bottomLayer">...</Widget>
<Widget type=Canvas name="middleLayer">...</Widget>
<Widget type=Canvas name="topLayer">...</Widget>
</MyGUI>

Each of these Canvas Widget has more elements inside. I've set up ToolTips, however, I only ever receive the 'eventToolTip' callback for Widgets that are inside the "topLayer" Canvas. I need to be able to get those events for Widgets inside the other two layers as well.

Any ideas?

Thanks,
David
