Hi Sven,
Welcome to forums...
The answer is YES
and very simple if, and maybe only if, you know how to write and read cookies.
Sorry cant really give code snippet...very busy at moment and been working 12 hour stretch...
I am sure though if you sniff around at some of the other examples, even in same section, Alf demonstrates how to save and read cookie values. (if i remember maybe even in tutorial section? ).
The basic process would be :-
in onload function
Is Cookie set?
Yes: Load state from Cookie
No : Load Default state.
and then give user option to save state at any time ([over]write cookie, delete it whatever).
Hope this helps
Alex
