I have Prinergy Evo 4.0.6.6 and have been using Acrobat 7 and Pitstop 7.52 and wanted to upgrade to Acrobat 8. After installing on my Intel Mac Pros running Tiger 10.4.11 and installing the plug-ins I did a test and the Kodak Separations Viewer will just......hang......I have to force quit. I tried uninstalling and reinstalling......same. Has anyone run into this?
