Proportional Editing Circle Gone

I am using Blender 2.49b, I am in Edit Mode, proportional editing is On (or Connected) I am selecting a vertex (or several vertices), and I have pressed G (or S, or R) to move the vertex. But when I do so, the falloff radius circle is invisible, and rolling the mouse wheel (or using PageUp/PageDown) doesn’t have any effect. Only those vertexes selected are being moved.

This is a brand new mesh, nothing but a subdivided plane, and I haven’t done anything fancy to the model yet. I rolled for a long time, and zoomed in very, very close, to make sure it wasn’t just tiny (I have seen other posts on the forums indicating that this could be a problem).

What’s going on here? How can I get the falloff radius again? Many thanks for any advice you can offer! :slight_smile:
