OK. It's a problem with the size of the nodes that is a static variable and when the user work with a mebn node before to enter in the global option dialog, the dialog search for the size of the actual node and find the size of a mebn node, out of range for the selection of the size of a ordinal probabilistic node. This correction correct the problem of the size when the user is working with mebn's and pn's in the same time.
