Right, but the problem is that the program is build on a class that needs table buffering to work well. From the moment i change the buffering status this thing starts to act strange. (even when i change it before the index an reset it afther the index)

So i have only 2 options : one is to find a sollution to change or create an order not using index on hoping the problem will be solved or te rewrite the hole class...

anyway thnx fabio
