Dear Mark,
Thank you very very much! It just worked!
I've (as you said) done so many changes while I was trying to get it work,
but I did not think about the options array.
Thank you so much, I've made the changes and everything works (IE,
Netscape, Opera under Windows & Linux). Just make me feel like when
will 'they' learn about CONSENSUS!!
Anyway thank you, and talking about 'Diambar' it's just the word
for 'Hero' in one of my national language (wich is Woloff, spoken in
Senegal - West Africa, where I am from).
Cheers,
- Omar FALL -
