Hello Purplegirl, some information about
this can be found on an old discussion. Unfortunately one of the participants (Lymester) has removed all her contributions, making the discussion a bit difficult to follow at times.
However I know that the thread still contains valuable information for you on the subject, so I suggest you look around in this info.
Good recovery to you.
