Hi,

We are facing the following problem in our XUL application:
- The "editor" tag is being used for Rich text entry.
- Need to show a balloon (with an arrow and some text) on top of the
editor(or iframe) element

Currently we are using Stack containing the editor tag and an
image+label(balloon) - in that order.  However the z-order of the balloon
(image+label) does NOT appear above the editor !!!

- Is there a way to resolve this issue?
- Can there be an alternate approach?
