with function :

video_window(vector(100,0,0),vector(200,1000,0),1,NULL);

I can create a borderless window over my desktop just like a layer. When I call this function again with other parameters:

video_window(vector(400,0,0),vector(200,1000,0),1,NULL);


the former window dissapears. So it looks like I'm just changing the properties of the same window instead of creating a second one.

How can I display multiple windows and change their properties (i.e. position or width)??

(running commercial version on vista)

I dont think that it is possible to run multiple windows, though you can create multiple cameras within a window.

that´s exactly what this function is doing->changing the settings.

To get a new window you have to start your application again.
You could use the function "exec".
