When initiated for the first time, the Workbench window tends to appear in a peculiar state. The window seems to stretch to fit the entire screen but might not be maximized. This generally happens, because the window takes the dimensions of the last application window you opened. To minimize such a window, ensure that the
Maximize
button indicates an unmaximized window. Next, drag the window edge (the cursor will appear as a left-right arrow
) to the desired width.
