Create the brain as you normally would, when you are asked for the file name put Defbrain,
When I have done this I have found and used the brain I have created with no problems.
BTW if you find that no one is answering your posts it may be that either no one knows the answer or they are looking for an answer.
I have found the people in this forum to be very friendly and helpfull with all the questions I have posted.
