problem with edit point

[fiddleman]

Hello, everyone.
I am using aliassurface on mac and I have a problem with the edit points; practically after drawing a curved edit point, you cannot move the edit points because they are not selected, they seem blocked.
How do I solve it for you?
Thank you very much.

Have you selected the "pick edit point"? which are different from the "cvs". . .
