Welcome to the forum.
You don't say whether or not you have AutoSyn enabled. That
is essential for what you want.
You also don't say which browser you are using. If it is
Firefox, it is a known problem. See Browsers on my site.
In Adobe RH7 it is fixed. At least it is on my machine and on
others that I have had some tests run on. However, there are a
couple of reports of people still encountering the issue.
