My investigation of Filemaker 13 on my Windows 7 computer shows that the Send Mail (use email Client) command does not work. I get an "the action cannot be completed because the other program is busy error. The only way I can retrieve the situation is to Force Quit Outlook using the task manager. If I open the file in Filemaker 12 the email is sent as I would expect. Has anyone else noticed this behaviour? Until I can sort this 13 will have to remain a no go area for my clients.
