If two people have an Activity open there is the possibility of losing data. If both users edit the Activity and save it, only the last changes saved are kept. The first one to save has their data overwritten when the second one saves their changes. This is a huge problem. If someone opens a Word or Excel document to make changes, and then another opens it - the 2nd one is opened in read only mode. Something needs to be updated in Redtail so that we do not have the ability to lose changes made to Activities!
