In Event, Participants, when you have edited a participants details and save, it refreshed and returns you to the top of the list. You should return to where you started. Currently updating the list is very very slow, as you keep refreshing to the top.
YES! This is maddening when you have 100s of registrants.
Workaround - create a participant query for the event and work through that list. It doesn't refresh to the top, unless you ask it to.
Yes, I agree. Very frustrating. Thank you for the workaround!
