I know you proper computer people don't play silly games, but I do and so does Bb
Angry Birds Friends, on facebook, has different scenes and these birds that you fire from a sling.
It's been working fine, but yesterday, it loaded as usual, the scene appears, all the little birds jump up and down, you can zoom in or out - but can't fire the birds
You hold the mouse on the bird in the sling, pull it back and let go to fire - but the mouse isn't doing any of that. It's the same this morning.
No-one else has had a problem so it must be this pc or mouse?

The only other games I play (candy crush saga and bejewelled blitz) have similar actions but are still working.
Any ideas what I could do to fix it?? Pretty please?
I want my go on the winter tournament, it's got snow cannons and everything

I'd empty my browser cache and delete the stored files. It sounds like one of the downloaded files is corrupted...

Have you fed the mouse Di? Some milk or cheese.... >>>>>>>>>>

As Suff says it could be a cached file, or you could unplug the mouse and put it in a new usb slot....

Okay TY guys , that seems to have done it , we did delete history last night , but have now deleted the files
