This is normal. Full-screen applications, also called screen-oriented applications, don’t actually scroll the screen at all. Instead, they use cursor control commands to move around a static screen. This means there’s nothing to scroll back to, as the screen hasn’t really advanced.

To test this, go to a command prompt in UNIX and run a few line-oriented commands such as echo or ls. You should be able to scroll back through all those. But if you use a screen-oriented application such as vi, that won’t scroll as you would expect.
