If any object in any of these other fields has the focus, then it
seems that messages don't get through to the other groups (whether
explicitly passed or not). I don't know if this classes as a bug, but
I seem to remember this behaving differently in previous versions.
(pre 2.3 ??)
One solution would be to make sure none of the other groups has the focus.
Another solution would be to put the keydown handler in the card
script, if this is feasible. (Easiest solution where possible.)
Perhaps Scott can confirm whether this is a change in behavior.
However, I remember checking this out once and writing a mail
describing the group/background message passing behavior.
I thought it went something like this when the first object receiving
the message was in a group:
object in group
group
card
other groups in order of layer, highest to lowest (i.e. "background" behavior)
stack
And if the card is the first oject to receive the message then:
card
all groups in order of layer (highest to lowest)
stack
But it seems that (in 2.3.2 anyway) when the first object receiving
the message is in a group, it's like this:
object in group
group
card
stack
