When browsing a host, you can also use the 'Get/Find More Results' option after the initial browse. Sometimes browse host might show zero files sometimes 50 for example, but a rebrowse or get more results might come up with showing more results from that specific host. That's how inaccurate browse host can be sometimes.
Browse host with LW 4 it supposedly selects the host at random from multiple hosts having same file in search result. With LW 5 you can select which host to browse.
