It seems that there is no way to send directly a data from DTpro to an email program. Even the Service (Send) is grayed out. Thanks
Have you tried the Export > Send To script from the Scripts menu?
The next release will (again) support drag & drop to the Dock icon of Entourage or Mail to easily create a new message.
Eboehnisch: your suggestion is welcome. It works very well in sending text, but not attacching files or pictures. Even translates pdfs in text.
cbrunerberg: thanks for the news.
