[OpenLayers-Users] Projection issues

Hello,

We have a basic OpenLayers setup with the most recent SVN code (checked 
out today).
We are using Kamap as a backend and the tiles are all pre-cached in 
mercator.

The problem is that the Latitude values are incorrect (when you mouse 
over a map area and look at the lat/long values). If you have a look at 
http://gpsdev.zonarsystems.net/test.html you will notice that the 49th 
parallel corresponds to 56 degrees latitude (off by 7 degrees), and the 
southern tip of mexico is 14 degrees latitude (approximately correct).   
Longitude values on the other hand are correct.

Additionally, when we try to jump to a location with the map.setCenter 
command (passing lat/long values) it jumps to a location on the map that 
is correct for longitude, but off again for latitude.

I'm a bit baffled and was hoping someone here might have some insights 
or ideas as to what could be causing this problem.  If you look at the 
source of the webpage above, you can see how we are initializing the map 
and layer.  You will notice we have created a new class 
(OpenLayers.Layer.KamapZonar) which is based on the OpenLayers kamap 
class.  We needed to do this because our kamap setup is slightly 
different and modified, but in general it's the same code.

Thanks,

Ben
