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.
Really don't see why it took so long. It was obviously caused by some code in an update that was not fully checked out.
We can only test so much and we try to test the things that affect the most number of customers (this one is pretty low) :).
In any case, this did get fixed. I was trying to find what update it went out in but couldn't find the exact one. Glad that it seems to be out there already!
