Saurabh, We received this message as well on our machines here. We are running Fedora Core 3 as well as RHEL3 machines with Adobe Acrobat 7 Reader, both display the same message. It appears that Adobe has changed the way they are handling certain PDFs, this error doesn't appear to any affect on reading/searching the PDF, at least from what we have noticed. We have just clicked the box to ignore the error message. As for the error message about the plugin, this plugin is no longer needed. Move the file out of the plugins directory under the users home directory and fire up IDL help, the error message should be gone, the plugin was used for Adobe Acrobat 5 Reader. Hope this helps. -- Douglas Ohlhorst douglas.ohlhorst@xxxxxxxx Systems Administrator II Phone: (303) 497-6581 NOAA/OAR/FSL/DD Fax: (303) 497-6014 On Fri, Jun 10, 2005 at 11:14:50AM -0600, Saurabh Barve wrote: > Hi, > > I just upgraded to Adobe Acroread 7.0 on an FC2 machine.
