Thanks a lot for your helpful tips.

I had a look at both files. The one that is ok with 2009-1 was edited with pimp-my-nav (not by me). I compared this file with the new one taken from 2009-2 and I realized where the differencies are as follows:
1. new category-id in group-id 2 (22 - 12 - 32)
2. new TPD-GRP (12 - 22 - 32)
3. new TPD CAT (12: 13 TO 15. 22: 23 TO 30 and 32: 33 to 39)
4. new data in ICONSDSC <category id> data tree for above mentioned items
5. new data in TPD-SEA <cat id> <search form file>
6. new data in TPD-SEARCH-ENGINE-VARIABLES etc

Said that, I am going to cut and paste and save a new lsc file in text format. I have just two point to clear:

- how do I fix discrepancies between .IDX/.URL files. I mean, some of the numbers that I would need are already in use in the new file. Example: in new file 0083 and 0084 are used for "college" but in the old one they are used for fixed cameras. How can I fix it? Just rename "college" or what..

- once I have the lsc file that makes me happy...how do I put my own POIs into the dbase?

Thanks for any help. (as tou can see I am improving..am I?? )
