The stack named "Before You Install" demonstrates the features of System 7 in a HyperCard window that greatly resembles the real system, but is only a demonstration program. Items that you would normally select with the mouse such as menus, icons, or windows, are just pictures, and are not actually interactive. If you try to use the mouse to select any items on screen, you get the following message: "This example desktop is for System 7 demonstration only. To move ahead in any topic, click the forward arrow, below."
The program displays the current topic at the lower left of the HyperCard window. On the lower right are buttons to help navigate through the stack (left and right arrows, Contents and/or Topics). If you can't see these items at the bottom of the window, it may be that the window is too low on your screen. You can't reposition this HyperCard window when it doesn't have a title bar.
To reposition the window, quit HyperCard (type Command-Q), and again launch the Before You Install stack. The title bar, "Before You Install System 7," should now appear at the top of the window. Use the mouse to reposition the window properly so that you can see "Contents" (the topic name) and the Quit button at the bottom of the window.
One other thing you may find is that Before You Install has no close box or button, only a Quit button. Since it is possible to have more than one HyperCard stack open with HyperCard versions later than 2.0, quitting will close all open HyperCard stacks.
The sample applications mentioned in Before You Install, such as MemoWriter and Let's Draw, are fictional and are not included with System 7 or HyperCard.
