Cutting along verticies.

I am trying to cut a face in 2 tris by using Knife(exact) and snapping on 1 verticular then snaping to the the oposite one and hitting enter but it just doesnt want to cut. Why is this happening?

Did you select the face that you are trying to cut?

You could also use CTRL+T Which splits a face into 2 triangles.

Yup the face is selected, are you sure you are able to cut through 2 verts? Cause ive tried plenty of times already and it doesnt seem to work.

EDIT: Never mind, I updated to version 2.48 (I had 2.46) and it works just fine now.
