onmousedown, onmouseup, onclick events aren't inherited. Neither is the clickable attribute.
Test case:
<canvas debug="true">
<trait name="mytrait">
<attribute name="clickable" value="true"/>
<handler name="onmousedown">
Debug.write('mousedown');
</handler>
<handler name="onmouseup">
Debug.write('mouseup');
</handler>
<handler name="onclick">
Debug.write('click');
</handler>
</trait>
<class name="myview" traits="mytrait" width="50" height="50" />
<simplelayout />
<myview id="blueview" bgcolor="blue" />
<myview id="tealview" bgcolor="teal" clickable="true" />
<button text="inspect blue events"
onclick="Debug.inspect(blueview._events)" />
<button text="inspect teal events"
onclick="Debug.inspect(tealview._events)" />
</canvas>

I can see why this might not work in 3.4 (and LZX traits are totally
broken in 4.x right now) but this _should_ work. Jim, I think we
should split this bug, because it is an important case to test and I
suspect the fix for 3.x and 4.x will be different.
