It works in the Internet Explorer browser
If you are using "Firefox" it doesn't
I'm not sure about Google Chrome though
Maybe a "Chrome" user can clarify that
Just tried it on my new laptop running Chrome and it wont let me yet on my old notebook running Explorer I can. Another computer I've used running Firefox wont let me either, so if you want to delete tags use Explorer!
Ah mystery solved.
Ok, those who don't use I E, when you tag your pic on the calendar, and need to re-do it, let me know and I can delete it for you. Remember to let me know the title of the event and the date it took place, and give me some idea which photo.
HTH
