We have been dealing with this, on and off, since 2013. When working in AE the users are copying and then dragging content from one location within a table to another. Using copy/paste with CTRL+C and CTRL+V reduces the jumping but the screen still does jump. Or pasting content within a new list item makes the screen jump. The user then has to scroll down to the original location to insert the copied content. I have opened a case with PTC but no solution as yet. Does anyone have any idea as to what would be causing the screen to jump? Has anyone else experienced this? HELP!
