I find that a container with bgcapture="true" blocks mouse interaction with elements below even when capture="false". I don't think that is the intended behavior. Is it?
Example: bgcapture test. Layers should turn blue when the mouse is over them.
Code
<layer name="layer1" type="container" width="50" height="150" bgcolor="0x00ff00" bgcapture="true" capture="false" bgalpha="0.5" align="center" zorder="2" onover="set(bgcolor, 0x0000ff)" onout="set(bgcolor, 0x00ff00)" />
<layer name="layer2" type="container" width="150" height="50" bgcolor="0xff0000" bgcapture="true" bgalpha="0.5" align="center" zorder="1" onover="set(bgcolor, 0x0000ff)" onout="set(bgcolor, 0xff0000)" />
