UV Pinning?

Having trouble with a couple of things, 1) Selecting an edge vertex selects corresponding ones so can’t edit just 1. 2) Moving a Pin is odd is there any kind of weighting ?

  1. On UV editor header disable the sticky selection or supply a simple demo file that clearly shows what you are talking about
  2. ‘odd’ ? Explain including a demo blend file that clearly shows what you are laking about. If you have proportional editing enabled turn it off. By default you select a pinned vertex and move it in the same way as any other vertex

Can’t find Sticky Selection. By odd and weighting I mean it’s overlapping when moved, however everything else around the pinned vertex area moves ok.

Had mesh selection sync on so was displaying less options. I really think there should be pin weighting, is there no way to do it ?
