How are you trying to present your Powerpoint slides? Are you saving the Powerpoint slides as a .pps format (see http://www.empirisoft.com/medialab/h...mtype.htm#pp)?
Also, make sure that you are using the most recent version of MediaLab 2010, v2010.3.102. You can find your version by opening MediaLab and selecting Help>About MediaLab from the menu bar.
Also, could you please give me the URL of the forum thread where it said that a 2010 version of MediaLab fixed this problem?
