Some little questions!!

[aborruso at spaziogis.it]

Dear users,
I have for you some little question:
- Is it possible to point to the label of an object (in example not to a
point) to go toward an URL?
- I have a  point layer with   SYMBOLSCALE 200000, MINSIZE 6, MAXSIZE 14
and I would not that the relate symbol in the legend becomes more or less
big when I zoom in or out. How can I do?

Thank you very much,

Andrea
