I cant reproduce. If you click the define button edit the connection and test it, does that work? try setting the connection to none the reselecting it?
if it still doesn't work, I'll need more details,
What version of Dreamweaver?
What extensions are installed, including version numbers?
Have you tried uninstalling Data Bridge and reinstalling it?
I dont follow what you mean. The from address is set on the first screen of the Universal Email wizard.
initialization string for line 1? i don't follow.
