I developed a database on an R6.5 server and my customers are using the R7 client. Some of them and I, myself, have had their Notes client crash while trying to make an update to the document (either while refreshing or saving it). Are there any design elements between 6.5 and 7 that I need to look out for that may cause this? This is rather urgent as the database is already in production. Thank you most kindly.
