iframe bug? content cut off…

hi all,
i am encountering a strange problem with iframe. we have an application built in Coldfusion, and in a few places the page has an iframe within an iframe (and set in a table tag). each iframe loads a ColdFusion page, not a static HTML.

when the content is longer than the height of the iframe, scrollbars appear (as they should..i have scrolling set to ‘auto’), but they only scroll part-way. About 1/2 ” is cut off from the bottom of the nested page.

any ideas? i’ve already tried forcing extra scrollbar length by putting a series of

and
tags at the bottom of the page. and yes, i’ve triple-checked that the table housing the iframe is set to 100% height.

please send some sage advice my way….

thanks,

gwen
