I have a PDF form that uses Acrobat 8 features. The form contains Javascript that interacts with the hosting web page.
Some of my Windows users have both Adobe Acrobat and Acrobat Reader, and Adobe Acrobat should be the default handler for PDF files. Users with Adobe Acrobat 7 cannot use the form, even if they can have Acrobat Reader 8 or 9 installed.
Currently, PDF is embedded as follows:
<object id="host" data="/path/to/document.pdf" type="application/pdf" width="900" height="550" ></object>
