I know how to change the current AppFrame:
```D
window.mainWidget = myFrame;
```
But how do I exit this frame?

I press the button, change to new frame, do the work, and now 
I want to return to the previous frame. How would I do this?

Saving the previous frame not an option?

It crashes if I reset it to the previous one.
```d
button.click = delegate(Widget src) {
    // window.mainWidget = homeLayout.child(0);
    window.mainWidget = myPreviousFrame;
    return true;
};

// crash
```

I think there was some kind of issue when changing widgets like 
that. Please try doing this instead:
```d
window.executeInUiThread(() => window.mainWidget = 
myPreviousFrame);
```

Also, please post whole code so maybe I can fix this later
