Proportional editing problem. Bug?

When I try to use the proportional editing tool, i turn it on, hit “G” to move a vert, but when i try to use “+ or -” to change the size of the area it effects, nothing happens. The controls work fine when i try to change the size of the selection tool (“bb”) but not with the proportional editing tool :-?
whats up?

Alt+ and Alt-, or Page-Up and Page-Down change size of the PET circle.

ok, thanks :slight_smile:
