Hello Tammy,
I just tried on SDM 12.7 primary (no secondaries) with Internet Explorer 10 and it does work - so the above guys at least aren't hallucinating functionality.
There was a few minutes delay, but that is to be expected. I was running with two separate instances of an SDM 12.7 client open. One Administrator to make the Announcements and one Analyst to get the pop-up.
Ideas:
* Try a different browser. Different version or type.
* Check that pop-ups aren't blocked.
* Try different client computer.
* Try directly on the primary server.
* The pop-ups ONLY work for Analyst interface say the notes, so check that your "Analyst" interface is actually an Analyst interface - I'm not sure what the code is checking as the specific trigger for "This is an Analyst." But see if you have an out-of-the-box setup - maybe head to a test machine.
Failing that, maybe open a Support issue for a remote session, as this falls into the "break/fix" category.
Thanks, Kyle_R.
