MessageBox & GuiControl

A question for advanced scripters out there....

Torquescript contains the MessageBox and the gui has the GuiControl.

However invoking these does not halt execution in the script that calls them: e.g.

function callBox(%this)
{
echo(">1");
MessageBox("title","comment","afterDoIt();");
echo(">2");
}
function afterDoIt(%this)
{
echo(">doIt()");
}

results in the following:
>1
>2
and then only when you click OK or Cancel .......
>doIt

The same thing happens when you do
Canvas.pushDialog(gui....);

the code just runs through and only halts when something invokes script again (like button presses)

This is a pain as quite often you want to embed these MessageBoxes/dialogs deep within the game logic and so I have to restructure complicated game logic to handle the code running on.

So my question is:

Is there anyway to halt the MessageBox() or Canvas.pushDialog() so that it doesn't execute the script immediately following it until the user has pop'd the dialog?
