Extended Dialog Example
Some People in SL are asking me, how to realize extended dialog menus (with timeout, dynamic content, sort-option, ...) Before i invent the wheel every week new, i will post my "best" code here, so ibn future i can simply refer to this page.

integer Sort = TRUE; // Should i Sort the List ?
// Have only Effect if Sort == TRUE; integer ReverseUp2Down = FALSE;
