Users of The Raiser's Edge Events Module can sort the list of participants based on the columns present. When you are using The Raiser's Edge 7.96 and click a column to sort the participant list, nothing happens.
This is resolved in Raiser's Edge 7.96 patch 2, applied to databases in Blackbaud Hosting Services in January 2017 and planned for download availability in February 2017. For further updates on releases as they become available, please see our Community Release page.
