Browsers -- Netscape and Internet Explorer (IE)
When a web page does not display correctly, it is often because the web browser being used is out-dated. The latest browsers can be downloaded from Mozilla Firefox, Netscape Browser Central or Microsoft Internet Explorer sites.
Plug-ins
If you receive a message similar to "Windows cannot open this file", it usually means that a different type of program needs to be installed. The SORA archives are provided in two formats: PDF and DjVu. No recommendations are made as to the quality of either format. However, DjVu files are around 1/4 the size of the pdf files; they will download much faster.
The latest plug-ins can be downloaded from the Adobe Acrobat Viewer or the LizardTech Plugins sites.
Errors Downloading or Viewing PDF Files
A common error message received when attempting to view Adobe Acrobat (pdf) files is, "File does not begins with '%PDF-'." Another common problem is for a file to begin downloading, but lock up before completing the download. Adobe offers a support page to help with several issues that may be involved.
