Dear Jon,

sorry for my late reply, I was on the road for some days.

This works perfectly. Even with disabled cache.
I guess this rules out DoS rules on the firewall.

I can't even see the '+' layer switch on this computer (see above)

What I can see are lots of warnings in the Javascript console.
Is this normal?

It starts with (when displaying openstreetmap.org):

Warnung: anonymous function does not always return a value
Quelldatei: http://www.openstreetmap.org/javascripts/prototype.js/1218150545
Zeile: 126, Spalte: 45
      case 'boolean': return object.toString(); 

Thanks in advance,
