Send Button Missing

I’ve activated the Send button feature and it seems to have some bugs. I’ve got XFBML activated and using the button count (like your instruction say), but the Send button isn’t there most time. I say “most times” because sometimes it is there and when I reload the post it’s gone. It’s there sometimes and not others. I can’t figure out any pattern or reason why it would appear sometimes and not others.

Any ideas?

Thanks,
JMR
