Brian,
Sorry about the confusion. I looked up your subscription. The widgets under your name don't seem to be appearing.. we'll get that fixed
The way the Likebox works is that the header is always a fixed height.. like 100px or something. Then, you can set the total height of the box in the paramters of the JFBCFan module. Any other height that's leftover will be used first for the Faces (if enabled) then for the stream. So, if faces are enabled, the stream is actually a fixed height, and the height of the faces will grow according to the height set. If faces are disabled, then the stream will grow according to the height.
So, what you'll need to do is (unfortunately) disable the faces from the Like Box/JFBCFan module and then set the height for however big you want the stream to be (+100px for the header, if you're using that).
Hope that makes sense, and that no faces is ok. Unfortunately, we don't have much control over the interior of the widget, so that's the best we can do.
Thanks,
Alex
