Randomly I obtain the following exception when I have many opened tabs, begin to close them one to one and arrive at the last one.

I hope that this is useful for you.

System.ArgumentOutOfRangeException: El índice estaba fuera del intervalo. Debe ser un valor no negativo e inferior al tamaño de la colección.

I haven't seen that one happen. Can you try and duplicate it in a small sample project and email that to us so we can debug it?
