The latest version of Adobe Flash (184.108.40.206) is causing some problems for Windows 8 users using the FireFox browser.
When downloading the EMS or EDF file you will receive a small message window saying "File generation complete. Click OK to save the file." After clicking okay to this message it appears that nothing happens. Normally you would see a File Save window. The File Save window has opened, however, it is not shown in front of the browser window.
To view the File Save window you will need to switch between windows by holding the Alt key down and hitting the Tab key.
