I've created a dialog that works great. Inside of that dialog I have a
button to popup another dialog. When the other dialog appears, the
original dialog is not disabled (grayed out).
In fact, the original dialog is a tabview. When changing tabs, the
child dialog disappears until I come back to the original tab.
Also the second dialog appears to be constrained to the browser, not to
the parent dialog.
I've tried increasing the z-index for the second dialog, but it appears
to have no effect.
How can I make the second dialog disable the first one and be
constained to the first one's area?
