oh dear, just updated and now the shoutbox appears on the vBA but sits there 'Loading'

worse than before.
Just to explain.
I am running vB 3.7.0b4 with vBA 3.0 Gold.
Both vB and vBA are installed to the root.
The installation is a mirror of my 'Live' site running locally on a Linux (slackware) LAMPP server. There are no other mods/themes/anything, just naked and clean installations. Getting same results from FF/Opera/Safari and IE6/7
