Hello Sidnei,

Thanks for your interest in the plugin. Let me answer you between your
lines:

Well, it is always a good idea if you liked your results. This way you can
reuse the classifier later on other images.

No, that part was not necessary. As you said, the classifier is already
active.

Can you send me the information that is displayed in the Low window,
please? That should help me understand how far the program went.

And I assume you didn't get any error message, right? That's sounds like a
bug... or a memory problem.

How much RAM memory do you have and how large your images are? That can be
the key.

If you want, you can send me your images so i can test on them myself.

Thanks for reporting!
