Since upgrading to Microsoft Office 2007 I now have trouble reading PowerPoint documents from a particular client.
Before I upgraded, I had no troubles reading their PowerPoint.
Now, I have missing fonts and graphics - so much so that many pages are blank, or filled only with a few dots and lines.
It is only happening with this one client - I have not had dfficulty reading older PowerPoints from others.
I don't have any problems with Excel or Word documents, only PowerPoint.
I have not been able to find documentation on this at the Microsoft support site, or via Google.
