The display of the IFrame, even if this is set to Height=0, will use 15 pixels in height.

For example, this could be a definition:

<iframe name="IFrameTransaction" id="IFrameTransaction" frameborder="0" width="0" height="0"
 scrolling="no" allowTransparency="true"></iframe>

So, if I use document.body.clientHeight, it might say 850. However, if the iframe line is not there, it will say 835. Has anyone found a way to include an iframe tag in a page without having it to take this default 15 pixels?
