The script step Send Mail terminates with:
Unhandled exception at 0x62863e90 in FileMaker Pro Advanced.exe: 0xC000041D: An unhandled exception was encountered during a user callback.
when running Windows 8, Office Home & Business 2013 and Filemaker Pro 12. As a note, I create the invoice db from the Filemaker db set. I think it has to do something with default mail service. Even if it does and there is something wrong with my environment, FM Pro should report the error and not terminate abnormally.
