Forum:Share not working

I've been having trouble "sharing" things for a while, i.e. when a baby calf is born, or if I reach an achievement level, or find a mystery egg etc. The box comes up with "Share" and "Cancel" but when I click Share nothing happens.

On very rare occasions it works then stops again. Yesterday I had three things within about 5 mins I wanted to share and the first two worked and posted to my wall but the third one never showed up.

Do I possibly have some setting in my browser affecting this? I use IE7 and I've also tried Firefox. I've also tried logging in to Farmville.com directly rather than from Facebook and nothing seems to make a difference.

Any ideas???

Thanks,

Kate.
