A blue title bar across the top of the main TreePad window contains, from left to right, the program icon, the name of the database currently open (tpx_manual in this example) and program name (TreePad X Enterprise 384 Gb (single user) in this example).
A single left click on the icon (or pressing Alt+spacebar) will open a small drop-down menu (known as the Program system menu) enabling you to minimize or close the program. Pressing Esc will close this window. Please note: double-clicking this icon will close TreePad!
At the far right of the title bar are the three standard buttons to Minimize, Restore and Close the TreePad window.
