proportional edit falloff v 2.45

Hey all!
I have the newest v 2.45 blender and have found that the proportional edit tool doesnt work like it did before! Has anybody come across this yet… or is there a new way to do it?

I’m using the 2007-09-15 build of 2.45 on a Windows XP box, and haven’t noticed any differences. There are some new falloff options, maybe you’re using one of the new ones?

How does it not work like before?
