Moving vertex not working on unity 4.2

Hi guys,

I'm using the free version of Gamedraw, I must first say I find the application very useful and is a great asset that Unity should have included by default :).

Recently, I updated Unity to 4.2 and since then I noticed that whenever I try to move the vertex of a mesh they dont respond, if I activate the editing mode and select vertex, I can see the gizmo to translate them, however even though the gizmo arrow selected turns yellow, neither the translation gizmo nor the vertex move.

Is this a known issue? Does anybody else experiecence this?

Thanks in advance!
