Ah so true. My bad I actually posted the wrong extent from the code. I have
tried about fifty different Extents. Now the extent is as it was posted in
the spatialreference:

maxExtent: new OpenLayers.Bounds(3050187.8969, 6585228.0377, 3761549.0272,
7803095.3519)

I calculated the resolution to be:

(3761549.0272-3050187.8969)/256 = 2778,754415234375

maxResolution: 2779,

This does not produce any good results either. I think I am missing
something simple... Scale, resolutions settings or something. I am sorry
about these complete newbie questions as this is my first work with
OpenLayers and MapServer.
