This doesn't sound like a problem.  Since the text will be a fixed 
size, you'll determine that size (won't you?) in pixels and therefore 
you'll know exactly how tall a windowpane-sized chunk will be.  You 
know the height of the text block, you know the height of the 
windowpane in which the text block is scrolling, and you know which 
chunk of the textblock you're currently showing.  When the 
currentChunk * (windowpaneHeight + 1) >= textHeight then you can't 
scroll any more.

If this model doesn't fit your situation, then perhaps you could give 
us a look at a demo page that truly illustrates your dilemma.

Regards,

Paul
