Steve (and others):
I just tried it, and also got the "can't be done" thing...I did, however, do a "cut and paste" into IE, without the ending period, and it worked fine. I think the problem was the period at the end of the sentence..here is the link again, without the dreaded "false dot".

Should work fine now..
Best,
