marker id errors

[aspa]

Hi there,
This is realy strange, sometimes when I load a marker it stays with id=0, some other times the id stays -1 or 5 (or 0 which I think it is the correct id for the hiro pattern), so smetimes my application works fine and some other time it doesn't detect the marker. What can be causing this? did I forgot some initialiazation or something else?
My application for now is trying to work with the hiro pattern only.
Any help would by gladly appreciated.

Ok, I've found that it is increasing the number every time I restart de application but not when start it for the first time, so the key is to know how can I restart the artoolkit without leaving the application. Does anyone know how to do this?

The problem is solved with arFreePat.
