Thank you very much for your help.
In fact, I have noticed the problem with graphing. But I didn't realized that
it is because of the holes on the collection.
Well, What should I do then? Seems that most of netviewrs let netview running
on other platform, but Windows.
Should I consider to migrate my netview to linux or unix too?
Cordially
