Looking on Help.Esko.com and do not find documentation for any Screen Manager software. Where is the documentation found?
From your Windows Start menu, go to your version of Screen Manager in the Esko tree. You will find shortcuts to the PDF documents there. You may have to 'Browse' from a popup if the PDF does not open immediately.
Alternatively, you may directly navigate to C:\Esko\bg_prog_screenmanager_vXXX\dat\doc to find the PDF documents.
