Thanks for the quick response. Here is how to duplicate the issue and a note on Chrome and the custom css override for the "old" button display issue you fixed...
How to replicate the problem:
1. Log in to the system as admin.with exisiting credentials.
2. Select Users in the admin menu and click "Manage"
3. Search for listowner9
4. Click "Log in as listowner9"
5. That will log you into the front end of the site.
6. Click the Flyout menu icon. (will work as expected)
7. Select "Edit Your Profile and Blog" from the menu.
8. Select the button "Edit your Profile and Blog"
9. Click the "New Blog" button which will show a form to enter a post.
10. At bottom of page, select "Cancel" to return without posting anyting.
11. Click "OK" to the message "Are you sure you want to Cancel..."
12. Now, try the flyout menu icon. (It will not work).
13. Click "Current Edition" in the top menu, that will restore the flyout menu icon functionality.
14. When finished with the diagnosis, click "Log out" in the fly out menu.
Problem occurs in Firefox current version and Chrome, others unknown.
Also, On Chrome:
I also noticed that Chrome is not loading the Custom css for the buttons where the original problem occurred.
Thanks for your help!
