Different product that you are referencing since your talking a 4 year old thread where as vb
4.2 series did not exist.
My suggestion would be in vb
4.2 series go to the vb
navigation mananger and make sure any links you have in there are full urls. If you want to use relative urls then in your vb
settings you definately want to make sure under the url section you turn on base url setting to yes.
