When adding threshold selection, it shouldn't automatically extract
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When adding threshold selection in the selection panel, it should not immediately extract (0,0). Instead, maybe it should bring to cursor into the next entry and have the user type values. Selection should be performed after the user tabs/enters out of the second box. Something similar should be done for when the user is changing values. Maybe extract the selection after all of the entry boxes loose focus? So if the user tabs from one value to another or adds new values, they should not be extracted until the user hits enter or clicks somewhere? Maybe we need an apply button?
