Net List Extraction Wizard lockup.

After review here are a few suggestions/comments:

1. All layer types need to be defined before running "Netlist Extraction".
Art001 --> Top
Art002 thru Art011 --> Internal
Art012 --> Bottom
Note: The other layers need to be assigned also such as "Mask Top", "Silk Bottom", etc.

Note: If a file is non-essential choose layer type "Grahpic" or "Temporary".

2. The Drill file was not aligned to the gerbers (this is a common occurrence), so you will need to use "Align Layers"
(a) Turn off all layers, except "Art001" (Top metal) and "Drl001" (Drill file)
(b) Goto menu: Edit | Align Layers...
(c) Select pad on layer "Art001" that requires drill hole (selection requires that you choose the edge of the pads).
Note: I usually always choose the bottom leftmost hole that requires a drill.
(d) Now select the corresponding drill hole on the drill layer "Drl001".
Note: You will see the layer automatically align-up

Now your ready to run "Netlist Extraction" (menu: Tools | Nets | Netlist Extraction...).

Note: This was a 12 layer pcb using line fills (over 300k total objects) and the netlist extraction took me about 1 minute.

I had all the layers assigned and the drill layer aligned in the *.WRK file. It locks up when running in version 3.4.1 but runs fine in 3.4.6. Upgrading solved the problem.

Thanks for the help Simon.
