Computer is running Windows 7. It is also using FileMaker Pro 10. Emails were sending fine up until a week ago. Bonjour and Java versions are what was installed with FileMaker Pro 10 (required). Updates have not been run on this computer. Usually when sending an email from FileMaker, TB will open a new window with the email that is being sent, and the user will click on Send. The new window does NOT open, and the email does not appear in the sent folder. I've also checked the win.ini file and made sure that the necessary settings are added. I've made sure that TB is the default program. I've restarted the computer. I've reinstalled TB. I've tried different accounts on the computer. All give me the same result. Any insight would be great.
