I have an issue which may or may not be the cause of a greater problem.
In the attached image you can see the vertices of a polygon cube and the vetices that i have selected and the edges connected to them are are highlighted in yellow, where as before only the vertices would change colour to indicated your selection.
Im sure that it is just a setting somewhere that i have unknowingly changed.
As for the potential other problem, i think i may have a lead.
Thanks, Roy.
