You can choose to make the updates manually by selecting the last option in the Help menu – Check for updates.

PDF forms are basically a computerized version of a paper form, which the user must fill out and send over via email, CD or publish it on a website. PDF forms are especially useful for e-books so that readers can test their knowledge by answering a test (in a PDF form), which is then sent to a server so that results can be estimated. They are quite simple, just consisting of blank fields or they can be interactive. The interactive ones are designed to be submitted on the Internet. The Form type is determined by the method of distribution.
The main multimedia formats that can be embedded are Flash, MPEG, MP3, QuickTime and Windows Media files. The activation of such content requires the reader’s approval in order to prevent playing multimedia from unverified sources.
