I'm trying to click checkboxes in a PDF that is loaded in a webpage. I've tried to use both SENDkeys and MOUSEclicks by x-y coordinates. Neither work well. Alignments, screen orientation, toolbars cause coordinates to move. SENDkeys doesn't reliably tab thru fields to get to the correct checkboxes. The info tool doesn't distinguish the checkbox controls. They are all: [CLASS:AVL_AVView; INSTANCE:15]   What is the best tool to click checkboxes in a PDF? thanks! Phil
