I just installed ezingbuilder 1.05 on Linux/Debian ubuntu 6.10(edgy).
If i now try to open a html file with the ezingbuilder html editor it opens
a new view with a message from Firefox telling me:

Unable to connect
 
Firefox can't establish a connection to the server at www.null.com:0.

Am i correct, that somewhere the starting code for the firefox gets a null value,
and firefox turns it into www.null.com ??
Any idea how to correct this ?

Thanks!
