One of my clients uses a Powerpoint template for all of their presentations which contains a company logo. The template and presentations work fine in terms of performance on Office for Windows, but whenever I open them on Office for Mac 2011 (latest patch), Powerpoint becomes extremely slow and essentially unusable. Opening the presentation, moving from slide to slide and modifying any slide takes 100% of my CPU (Intel Core i7, 4gb RAM) and each action can take anywhere from 3 to 30 seconds. If I delete the logo from the template, this behavior is fixed. As this is a large corporation, I will not be able to convince them to change their template. Are there any solutions or fixes to this problem that someone can help me with? Thanks for any help!
