Problem w/ toolbar

One of my students has no toolbar showing at the top of the drawing view/camera view window (the icons for Show Grid, Grid View, Show Previous, etc.) I’ve tried to find out how to restore these buttons via the help files, and have found one suggestion that I go to Window → Toolbar. However, I don’t see Toolbar under my Window menu. Any tips on how to put those useful icons back above the drawing view?

In version 3.5 the Toolbar options are under View>

They are under Window> in version 4.

Sorry, I don’t have other versions, HTH,

Paz
