Name Field Cleared - Enter as Guest

Hi

When guests are entering my rooms, they click on the radio button "Enter as Guest", type their name into the text box and click “Enter Room”.  Their name field is then cleared out to blank.

No matter what content is entered, it gets erased and users remain at the log in screen.

Internet Explorer is our default browser.  Users have their pop up blockers turned off.

At first this was random.  However, it has become very consistent for the past few months.  I called  in December and was told to use Chrome. 

Chrome’s not my preference as Citrix works better in IE, and having to open Chrome specifically only to log on to Adobe is rather frustrating.  

Does anyone else have a real FIX  for me?

Thanks soo much!!
