I am trying to troubleshoot something and they used a sink as a trap for events. I need to look at the labels while things change. The minute I switch to another view (table, tree, etc) the sink object closes. It has a very small header so you can't grab it and move it. Neither protect or no select are checked. It is extremely frustrating. WHY would you do this? Why are source/sink special so that you can't work with them?
