eTRM uses javascript that opens and focuses a separate window to display reports. Your browser does not appear to support javascript. This should not prevent you from using eTRM but it does mean the window focus feature will not work. Please check the contents of other windows on your desktop if you click on a link that does not appear to do anything.
