This is really neat. Think of the following:

ratioBits := (sBarTop.Y-sBarBot.Y)/ABS(sBarMax-sBarMin)

value := ratioBits * (sBarTop.Y-sBarBot.Y)
(This is all from memory, so I may be mesing it all up....)

value is the height in pixels of a scroll bar "page". This is also the
elevator height. QED. (Again, I think that this is wrong, but I don't got
time now to look it up, ST:TNG is starting...)
