A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
PowerPoint for Windows has a Grid and Guides dialog box that can be opened that can be opened from the View menu in the group that has the Ruler, Gridlines and Guides options. In that dialog is a checkbox called Display smart guides when shapes are aligned. Unchecking that prevents the object snap you see. Unfortunately, they have never added that dialog to PowerPoint for Mac, so there is no way to turn off that feature.
