I answered a question recently from someone who was having a problem getting a web site (not mine) to work properly. In this case, he referred to the Foxit web site. Foxit is the maker of Foxit Reader, a much smaller and faster alternative to Adobe Reader.
Foxit also offers a number of add-ons for the free Foxit Reader to enable it to do many of the functions of the expensive Adobe Acrobat .pdf creator and editor. The free Foxit Reader is my choice for reading PDF files.
He wrote that he wasn’t able to use the entry boxes on the site’s web page
I see the same thing that he saw, when I used IE7, Firefox and Opera, except in all of them I see the Product field as its normal length. The four items Product, Version, Build and OS are not reply fields into which you can type. They are pull-down —option— boxes — notice the pull-down handle at the right end of the boxes..
I suggested that he check the site again and see if it have values for Product now, just in case Foxit had been editing the site.
