Hi Paul-

I was unable to reproduce your problem, but wanted to pass along a couple
of suggestions; try these and please let us know if they don't work.

1. In the slice viewer, click on your label map. Go to edit properties. In
the Display tab on the left hand side, make sure that your colour table of
choice is selected.

2. In the Editor module, under 'Edit Selected Label Map', make sure that
when you click on the label box (the one with the colour), it has the
correct colour table referenced (this is the 'Color Select' box).

Making sure that these things were properly selected for my colour table
got me correct results.

Please let us know if you run into more problems.
