Proportional editing?

For some reason the - + keys no long work (after reinstalling windows) when the O key is active, if I hit the - key or the + key nothing happens, and numlock is off? any ideas

(after reinstalling windows)

No, since 2.37 only the mousewheel works.


ah ha!, ok thank you I missed that
thank you! duh

I see Page-up and Page-down work too.
