Thanks, . We are still at SP2007 and QWP 5.2. I don't know of any list size limitations.
Back when I was working with Quest on the case associated with this, they acknowledged an issue with some of the legend data on the charts but could never reproduce any report total issues like what we had. It has been many months since we were dealing with this so it will take some time for me to dig up the scenario and give you specifics on what we saw. Will do so as soon as I can. Thanks again!
