I've seen many blogs highly recommend using a grid like 960 for prototyping in newer version of Fireworks.
I'm using CS6.
When I create a new fireworks document from template, I select the Grid12.png, 960.png, etc. When I try to add objects to another layer, they are not snapping to the guides or the vertical grid paths. I've enabled snap to grid, guide, smart guide, 9-slice scaling, etc.
I would assume that most people would want the ability to snap to these guides. Am I missing something?
