Hope you receive an answer from GR Barbara.
It'll be interesting to hear what, if anything, they have to say on the matter.
I also have had a little play and as someone on here suggested, I tried the Aust GR site and had no problems - as long as I didn't log in.
The same applies to the link that you have just supplied. All works fine - until I sign in.
I'm sure there's an easy answer somewhere somehow for us.
