Hi,
when hidden
what means "when hidden" in this case?
is "visible" of the child set to "false"?
alpha="0.0" itself is not enough not make a element really hidden,
the enabled="false" for children elements doesn't work for the visual shape itself,
it disables the element itself but when the visible shape will be part of the parent and still be clickable,
a hint to make children elements not clickable would be to use the "pixelhittest" setting from the 1.0.8.14 version, then only the image/shape of the parent element itself will be checked,
best regards,
Klaus
