All of our buttons work fine accept for Google+ in IE9 when compatibility mode is on, which then causes the browser to ignore the g:plusone:count="false" code and displays the counter which then throws off the layout.

Thanks for pointing this out. Several other users have brought it to our attention so it's likely a bug on our end or a change to Google+. We're currently working on a fix.
