I am in contact with my ISP's support, but when I tried to reply to them I could not see a radio button to post it. Its existence was proved by someone, and when I created a pdf of what I saw, there appeared the basic hyperlink (without all the decoration). Using that I managed to post my reply. I use Control+F5 to clear the cache and IE as well as usual FF. Still no visible button.
Any more ideas from fellow members, please!
