Can't add Technicians

Can't add Technicians

I have just installed the 4.6.0 version with Build number 4681 and I am having trouble creating Technicians.  Whenever I click on either the View Roles or Add Technician button on the Admin tab, nothing happens.  I'm running this on a Windows 2012 R2 server using IE 11.  Any ideas as to what might be causing this?
