lnBodyClientHeight=document.getElementById("FournierTransformationList").clientHeight resizeTo(lnBodyClientWidth+10,lnBodyClientHeight+29)Where 29 was the necessary amount of pixels as per the extra height pixels required to properly show a window. However, XP allows the user to change the window title bar height. So, this causes some weird effects. Anyone knows a better way to calculate the window height which would take care of any XP window title bar height?
