External Manipulation of Text Fields/Variables, etc

Here is what I want to do…I am creating a Flash movie built on top of a C++ shell. I can FSCommand out to the C++ code to do certain things, but I want to be able to dynamically update the Flash movie to, for example, keep the user up to date on what might be happening.

So, maybe 10 or 20 times, I want to update a status field. The problem is that when I set the variable (externally from the C++ code), the Flash movie does not immediately update. I have to (A) Go to a new screen then back again real quick. What I need is instant updating, or some way to signal a redraw to that screen.

Has anyone done this before? I am desperate for info!!!
