Has anyone reported or seen an issue where when a user tries to login to the enrollment section, after entering their username/password/domain incorrectly, the dropdown list disappears?

 

 

I looked at the User Attempts Log, and none of the failed attempts show up in the log. Only after the user refreshed and logged in successfully, was anything recorded in the log.

 

I suspect something is causing one of these popups, and after the user clears it the dropdown doesn't re-appear. (When the popup comes up, the list disappears).

 

I'm running build 5100 so a few versions behind. Has this issue been corrected in newer versions?
