It seems that scroller doesn't work very well with ajax reload.
I have been able to prepare an example of the issues I am facing at http://live.datatables.net/lukacupe/1/edit .
When I reload the data when the table is scrolled to the bottom the begin of the count at the info footer doubles its value.
Otherwise, if I scroll to the middle of the table and then I reload the data the info keeps the same pagination information but the table can not be scrolled upwards.
