Hi Adam,Sorry it has taken me a while to reply; I have been away from my
precious Mac for a couple of weeks (it's been tough! :))

When I ran the ruby code you suggested I got:

*ServerListViewBrowserItem#imageRepresentation: ArgumentError: invalid value
for Integer: "root"*

* /Users/tom/dev/proj/bonjour-graphviz/gui-tools/mac/ZeroConfNetworkBrowser/build/Debug/ZeroConfNetworkBrowser.app/Contents/Resources/serverlistviewbrowseritem.rb:42:in
`NSFileTypeForHFSTypeCode'*

* /Users/tom/dev/proj/bonjour-graphviz/gui-tools/mac/ZeroConfNetworkBrowser/build/Debug/ZeroConfNetworkBrowser.app/Contents/Resources/serverlistviewbrowseritem.rb:42:in
`imageRepresentation'*

* /Users/tom/dev/proj/bonjour-graphviz/gui-tools/mac/ZeroConfNetworkBrowser/build/Debug/ZeroConfNetworkBrowser.app/Contents/Resources/rb_main.rb:26:in
`NSApplicationMain'*


It would appear that NSFileTypeForHFPTypeCode is expecting an integer value
instead of 'root'.


Any ideas?

Many Thanks,

Tom
