When ECMap is installed, the default is to have the icons appear on a toolbar across the top of the window, underneath the menu options.
To have these icons not display, choose Toolbar from the View menu. Toolbar is cleared, and the icons disappear.
If you choose Toolbar again, the option is reselected and the icons once again appear at the top of the window.
The icons that appear differ, depending on whether the current map is a transaction map or an any-to-any map. If the current map is an any-to-any map, there are no company or trading partner icons.
