We have developed a custom opportunity closure screen using lightning component. It has HTML elements such as readio buttons,  custom buttons and text fields.  When specific users navigate through the screen, the elements appear to be frozen and user is unable to provide any input.  The backend page inspection shows that the users inputs are getting recorded.  e.g. changing radio button option does not appear on screen, however on mouse click it changes the field values (set in console.log).
The issue is not recorded if the same functionality is initiated by System Administrator user or any other user.  This is critical issue for our lightning go live.
