Hello, brijazz.

Well, first of all the Client Associations thing works the opposite from the way you imply.  The Client Association does not appear until the item is exported.  Thus, the lack of Client Association is just another symptom of the problem, and will not lead to the cause.

The bookmark in your question has a quite normal URL which should be exported to all browsers, and I'm at a loss to explain how it could be imported and not exported if you did not touch any of the advanced settings in Settings > Client or  Settings > Agents.  Clues may be in the Logs; menu > BookMacster > Logs.  If you scroll back to when it was working, you will see how each Import operation is immediately followed by three Export operations (to the three browsers).  Also, of course,  check the Errors tab in that Logs window.

If you don't find the cause in there,

• Note the time on your computer's clock.
• Add a bookmark in Firefox.
• Wait 5 minutes or more.
• Activate BookMacster.
• Click in the menu: Help > Trouble Zipper.
• Follow the instructions given by Trouble Zipper.  The more data you choose to include, the better.  When it comes time to edit the email, tell us the name of the bookmark you added in Firefox, and the time you did so.
