on openStack send "rollCredits" to field "Credits" end openStack

# Description

Handle the openStack message to change a stack objects, or perform other updates, when the stack is opened.

The openStack message is sent after the stack is visible.

To make changes that take effect before the stack becomes visible on the screen, use a preOpenStack handler instead of openStack.

The actual opening is not triggered by the openStack message, so trap the message and not allowing it to pass does not prevent the stack from opening.
