UV vertex moving messed up *Probably an easy question*

[Poethetortoise]

Hello I was working on my Portal test chamber render when I was about to uv a cube when I tried to move a vertex and there was a circle around my mouse and it was a totaly different way of moving the vertex

Sorry if i am not explaining that well here is a picture of what i am talking about



The circle around the mouse is what im talking about. How do i get out of this mode?

that seems to be UV > UV Sculpt option, which is enabled
