OK, found out what it was – but how can i use pretty urls?

By rediting the config file to short urls false the problem has gone away:

$bb->mod_rewrite = false;

So, why if set to true isn’t it working. What happens is the directory mysite.com/bb/topic (say) goes back to the home page of the main blog at mysite.com
