I can't figure out a way to show two or more windows at the same time. If I use the CreateWindow(...) function then I get errors, and I can't distinguish between the controls and messages for each window, and if I use Dialog Resources, then once I invoke one of them, it waits for it to close before it invokes the next...

Is there any special way to do this?? I only want 2 windows to be shown and active at the same time....
