When I test an HTML email the "Test Send" window does not always close. It leaves the window without controls to close it. The only way I can remove it is to completely close Filemaker.

Does it seem like it is having trouble connecting to your mail server? (There is a 60 second time out you can change on the Users / Mail Account tab.) Another way to close it is to bring up the script debugger if you're using FileMaker Advanced. That should let you stop the script and see where the problem is. FWIW, I can't reproduce this even testing offline, with bad mail server settings, etc.

John, It connects and sends the mail ok then says it is Disconnecting and that message stays on the screen until I close FM. It does not do this every time so I will see if I can isolate exactly when it occurs. I also have Advanced so I will try and debug the script. BTW I'm testing on a Mac with 10.6.4 Thanks.

Cool. Let us know what you find.
