It is not yet fully understood and is a source of systematic error for W-boson mass and width measurements in hadronic \WW decays at LEP2. The methods of measuring this effect and the results of the 4 LEP experiments at $183\gev\leq\rts\leq 202\gev$ will be presented.6 pages, 1 table, 7 figures, Symposium, ISMD2000, Typos fixed (proof reading by editor)High Energy Physics - Experimenttext
