Does anyone know of a current or soon-to-be-updated mapviewer that works with the 1.1 update?

I personally love playing with a mapviewer (I've used TerraFirma for the previous versions), however mine does not work with 1.1 (crashes when I try to load maps now).

Anyone know of anything usable? Or am I going to have to wait until one of the current ones gets updated?
