two images with the same ID

The problem is not that there may be no image with a certain ID. It's the
opposite: my application has 2 images with the same ID (see Subject). They
are in different substacks, but when assigning an image as a button's icon I
am not allowed to indicate the substack--as far as I can tell I can only use
the numerical ID of the image. So LC decides which of the two images to use.

Terry said: " You can just give your imported image a different and
non-conflicting id using the property inspector." Changing the ID of an
image is risky because the image may be assigned to something else (like
another button) with that ID, and you'll break that assignment if you adjust
the ID. With just a few images and buttons you can mess around and fix this,
but what if you have hundreds of images and a bunch of duplicate IDs? This
can't be right... 

If using an image ID is the only way to assign the image to a button, then
the IDE should not allow duplicate IDs in the same stack file, even if they
are in different substacks. (Unless I'm missing something.)

Is this a bug? a corrupted stack?
