Nelson,
I'm not exactly wure if you're talking about the LikeBox/JFBCFan module or the Like/Send buttons, but below are some suggestions depending on how you're configuring things.
For the Like/Send buttons, you can use the Content Plugin, which comes with JFBConnect for automatically inserting the Like/Send/Comments to any content section of your site. In the configuration area, there is a "Show In Category View:" setting, which you can set to 'none' to hide it in those views.
If you're using a module to display the widgets in a specific Menu item, there's no way to exclude specific types of pages from displaying that module within Joomla. As an alternative, I'd recommend that in the article you want the Like-Box/JFBCFan module to display, simply enter the following text in the article itself:
{JFBCFan href=http://www.facebook.com/sourcecoast}There are other parameters you can use in this tag, which you can find in the
JFBConnect Tag Configuration Guide
As for the box opening 'down', there's no way to change that behavior. It's a function of Facebook itself, and we have limiting control over it. They do that so we can't 'trick' users into sending or Liking things that they don't want, but every once in a while, it causes issues like this that are unavoidable.
Hope that makes sense, and the best we can recommend is putting padding on your footer to make it larger which can accomodate the 'growth' required by the Send button.
If you need anything else, just let us know!
