I have the "refresh" symbol on some of my slave sites. I opened and clicked 'Save' on them but they STILL show the refresh symbol. What is my next thing to look at or fix so I can make sure its updated?

The refresh icon is not critical.

This is just an information that show you that you have different number of tables between you current slave site and its parent website (the one that is defined in the website template).

The idea of this "refresh icon" is to let you know that you have installed (or removed) an extension in a website and that another website does not reflect this modification.

You can analyze the reason when you go in the JMS Tool menu and click on the slave site that has the "refresh icon".
When you go in the "table" tabs, you can see the list of table (or links).
If you have a difference between the "template" and "site" column, this explain why you have the "refresh icon".

Thanks for the nice info. I am able to tell now what tables are different etc.
