Multi-select problems on events in ‘Behavior of Element’ window

Hey ForeUI, your tool is fantastic. It is helping us do a lot of rapid prototyping on a .NET rew-write we are working on. One problem I have encountered is that when trying to multi-select Events in the ‘Behavior of Element’ window to copy down to the next Case item, I successfully hold down the Shift and right click with the mouse on 3 of 5 events and then it forgets that I had those three items clicked. Not sure what is going on.
