[OpenLayers-Users] Projection Problem

[George Mu'ammar]

Can you describe when is it that you see all of it and when is it that  
you see half. Do you do some operation (like pan/zoom) and then you  
see only half ?

or is it that if you refresh the same page sometimes it draws all the  
map and sometimes half ? in this case it could be a performance  
problem of mapserver.

What exactly happens when you try to pan ? in what sense you are not  
able to pan  ?

Is the map online ? can we see ?

Sorry too many questions
