I have purchased a code signing certificate from Thwate...it works fine for
any workbooks that I develop and publish to other users they are presented
with a request to accept the ceritifcate and proceed....thereby removing the
annoying enable macro's question.

I have one workbook that creates a new workbook based on an existing one and
then emails that new work to other users. When this workbook is used by other
users the certificate credentials do not get copied and saved with the new
workbook.

I have tried just re-saving the existing workbook on the users PC and it
still seems to lose the credentials.

Can someone point me to information relating to code signing certificates to
address this problem.....the objective is really to remove the need of the
user to select the enable / disable marcos selection and in Vista to be able
to open the workbook within some security still enabled...

Any help appreciated....
