Thanks Ben and Nancy.
I've tried both suggestions but without any success.
I'll keep trying.
Try using a different browser that allows cookies and does not have script blockers.
It would seem Internet Explorer works once I make it the Primary Browser.
It now also works when I put it back to Secondary Browser, but Firefox still gives this issue.
Nancy, your post gave me an idea that works.
I deleted Firefox from my browser list, then added it again. Works fine now.
Thanks to everyone for the help
