welcome to the forum!
I have sent a new "twviewer.swf" to you by email, please put it in the folder "resource" at the installing directory of the program. Then check if it can fix the issue.
And there is another way to difine where these hint show, you can add a "text area", let the hints show in the text area.in the "text area" properties panel, access the "list values'option, there you can difine the content of the text area. This effect can be seen in the sample project "lijing garden".
