[Plugin: Sharedaddy] Button are appears only on pages

Hi,

I’ve just downloaded the last version of the plugin and it looks cool.
But for some reason the buttons appear only on pages and not on posts.
What can be wrong?
(More than that, I would like them to show only on posts and not on pages, and I saw it’s is not supported by the plugin’s option)

Another question, is there a template tag/function to use if I want manually place the buttons in a certain location of the post?

Thanks,
Maor
