Since it was me that Maria was very kindly helping I can vouch for this tutorial.  I successfully created a fractal with a masked layer for the first time after going through this tutorial only once!  Maria - you're a star!  I sincerely recommend anyone having masking problems to have a look at this tutorial as I'm sure you would find it most helpful.

Thanks again Maria for all your help.
