We are currently using Office 2010 on all of our computers. All users create PowerPoint documents and share them with one another. The documents show up correctly on three of the four PC's. On the PC that is having the problem the text will not align with the text box, it will fall out of the bottom or overlap words. I have attempted changing printer drivers, checking if they're using different fonts and repairing the office installation. I'm not sure what else I can check that would resolve this issue. Any input would be greatly appreciated. All other documents such as Word and Excel function properly.
