Sorry, I didn't give the full error message (example from clicking the 
link in my previous post), is:

Error starting URL: Failed to execute helper program (Invalid Argument)
(Command was: rundll32 url.dll,FileProtocolHandler "http://gtk-
win.sourceforge.net/")

Typing the given rundll32 command in at the command prompt opens a web 
browser on the requested page as expected.
