Resizing layers in Firefox

Hi all,
 
I have made a webpage that partly uses a javascript to resize a couple of
layers so that it will fit to the window when the window gets resized.
This works fine with IE, but in Firefox nothing happands. Does anyone know
how or if it's possible to do this with FF?
I don't get an error in FF - it just seem to ignore it... :-(
 
The script uses styles for setting new sizes, f.ex:
-----8X--------------
 var mLay4 = new getObj('frmWorkarea'); // Custom (Quirkmodes) function (to
get object for the different supported DOMs.
 mLay4.style.height = wh;
 mLay4.style.width = ww;
-----8X--------------
(note: replacing the getObj() with checking for DOM in place makes no
difference.
'wh' and 'ww' are precalculated sizes based on window-geometry.
 
Regards,
Kenneth
