Message	Make sure that the spatial reference of your dynamic layer matches the Map your are trying to magnify. Just a side-note: There's also a control called "MagnifyingGlass". This control uses a different way of loading layers that is more intensive image loading, and therefore is limited to only work with tiled services where this is not a concern. I just want to make sure that when you say "Magnifier" you don't mean this other control. Magnifier on the other hand loads an image that is [magnificationFactor] * the size of the map. Ie. if your map is 500x500 and the magnification factor is 3, the magnifier behind the scenes loads an image of size 1500x1500. At some point it is likely that the size of the image will hit its maximum size and error out, depending on the size of the map and the zoom factor.

Message	Well as the problem was de zoom factor, any ideas about how to make it work with a decent zoom factor. Let's say 3. The solution only allow me to work with 1.5 as zoom factor.
