Selection issues?

I’m having trouble getting out of this select mode with this red circle in the UV image editor, I recently jumped from 2.49 to 2.6 (big jump, I know) so I’m not sure how to get out of this, any ideas or hotkeys? Thanks in advance.


Looks like paint select mode. Press C.

It actually turned out to be UV sculpt mode, which was checked in the view menu, but thanks!
