Thanks for your reply. I have been studying what you said and trying to work out how to implement it. However, I am still stuck. Could you provide any further explanation?
My main problem is that, when searching for help, there is still very little that is specific to v 5.0 and file names and locations often seem to be different or, if a file is found in the right place it does not contain the expected code - probably it is somewhere else!
How much is v5.0 different in structure from previous versions? Do features and files tend to stay in the same place?
Thanks again
Colin
