My first question was why you have an openCard handler in a "stack-in-
use". It would seem to invite management problems, as it will trap
*any* opencard message. (Apart from the fact that the Rev IDE consists
of rev stacks, what would you expect to happen if you had two projects
open at once?)
I cannot work at all if i can't trap messages between stacks.
When I've built projects with multiple stacks, I've tended to create
all the stacks as substacks of a single mainstack. The mainstack may
have no user interface at all (hidden), but it can be used as a place
to trap events for all the substacks in the project. So you can place
an openCard handler there and be sure it will only trap openCard
messages originating from the stacks in the project.
I don't know the nature of your project, so this idea may not be
practical. But I'd suggest trying to avoid placing handlers for
navigation events (openCard, etc.) in a stack-in-use.
Cheers
