The stack widget was not finished and does not support z order. Stack needs to 
implement this to support skins. Currently Aqua uses stack extensively.

Estimated time: 1 day

1) If you place 2 views on top of each other in a stack. You can not click 
through them to any content underneath. 
2) Any content lower on the stack that has views will appear to be on top on 
anything later in the stack both visually and mousewise. This is not what is 
expected and will cause major problems when people start using views in stacks. 
Examples are anything with opacity, splitters, or iframes.

spoke with evaughan, this will take a lot of work and a lot of widespread changes 
to fix. i really don't think a) the work will be done by mid-july and b) we want 
to land such big changes before mid-july.

nominating for beta3, removing from beta2 radar, pushing to m21

nsbeta3-, aqua can wait.

Comment 13

[Eric Burley]

I suspect this is caused by the same thing:
given the following xul:

	<stack>
		<vbox>
			<box height="100"/>
			<splitter  height="10px"/>
			<box height="100"/>
		</vbox>
		<bulletinboard>
			<text top="100" value="this is a line of text"/>
		</bulletinboard>			
	</stack>

 the splitter hides the line of text, which should be visible.
