Problem with starting new parts

Hi all,

I am half way through an aseembly and something changed.

Now when i start a new part in the assembly

  • the cursor doesnt highlight which face i want to select.
  • when i start a new sketch i can no longer highleight a vertex when i run the cursor over the top.
  • the other parts do not go transparent when i start a new part within the assmbly.

Please let me know what has ahhpened and how to fix it.

I need to get this drawing completed today.
