If Flash is not installed on your system, or if you have a version of Flash earlier than 10.1, the Copy References to Clipboard button is replaced with the Select All References for Copying button. For security reasons, browsers require an updated version of Flash in order to access your clipboard, so in order for Edifix to copy your references directly to your keyboard via the Copy References to Clipboard button, you need Flash 10.1 or later installed.
