You should note that Quad is part of Innoveda (however you pronounce it) and
Incases was bought by Zuken (formerly Zuken-Redac).
 
We (Quantic Labs) trade under the name Quantic EMC.

Just thought I'd clarify. I also endorse Fred's comments, although I would not
necessarily agree that the problem set needs to be simplified.
Users should not expect miracle software! Ask Microsoft about that!
