My apologies if similar questions have already been answered on this forum but I am puzzled by something. My main project contains about 6,500 people, and over 1,000 external exhibits. It works a treat, with almost instant response to all actions - edit, filter, etc. I have another small project, of about 370 people (about 450 names) and only 50 external exhibits. On this project everything is slow - when I ok after an edit it takes a couple of seconds at least to respond. Updating the people explorer after adding a person takes a long time. Selecting a letter from the index on the project explorer again leads to a long delay. I've optimised, reindexed and checked file integrity many times. There are no problems highlighted. Is this something others have encountered and overcome? If so, any suggestions would be welcome. Tom Coughlan
