Ok,

just noticed now that if I select ANY of the UVs in my torso map, it is selecting the UVs in the hand and leg too. In fact, even if I drag over an empty space on the UV window, it selects these vertices. It's ok if I select them in the scene view. The edge on the groin is no longer selecting the edges elsewhere - though I haven't changed anything.

Should I just carry on and map the legs and arm later and this may sort it out?

Also, could having an extensive history that I've not deleted be causing instability?

cheers,

gubar.
