In the Investments View, on the Equities Tab, double clicking an equity edits it, and right click brings up the context menu for all available actions. In the Securities Tab, double clicking or right clicking have no effect. The only possible actions (Edit or Delete) are only available through buttons at the upper right of the display. The two tabs should behave more consistently. Either buttons for all available actions, or context menu for all available actions with double click for edit.
