Why does text stop halfway through page?

Why does text stop halfway through the page? No matter what alignment I click nothing changes.

Thanks

Looks like a right indent character was set for that paragraph. Try showing the ruler (Format->Ruler) and selecting the paragraph(s) that comes up short. You should be able to drag the right indent character off the ruler.

That worked. Thanks Rdale.
