If you select Cascade All from the Windows pull-down menu, the windows are all offset from each other and overlap, as shown below.

The agent window consists of smaller sub-windows, each of which can be displayed or closed as necessary. By default, windows are stacked vertically in the agent window.
Each
time a window is selected for viewing it appears beneath the previously
activated window. To close a window, either click the close-box tab at the
upper right hand corner of the window (r), or de-select the
window in the pull-down menu-bar lists. The window closes and the other windows
fill in the spot it occupied.
To resize the agent window to
exactly match the windows displayed, click the Pack icon (
)
or select Pack from the View pull-down menu.
