"Event is not defined" bei Firefox

[Master_of_Magic]

Ich hab ein Script von DynamicDrive auf meiner Seite, dass eine analoge Uhr neben dem Mauszeiger anzeigt. Das geht auch alles einwandfrei im IE. In Firefox bekomme ich jedoch die Fehlermeldung "Event is not defined" in Zeile 195. Ich weiß, dass das Skript nicht für Firefox geeignet ist, da dieser die Events irgendwie anders verarbeitet. Aber kann mir einer helfen, wie ich das zum laufen bekomme?

Hier mal das ganze Skript (Zeile 195 ist gekennzeichnet):

//Clock script
if(clockenabled != "0") {
dCol='0080FF' //'FF00FF';date colour.
fCol='00FF00' //'FF00FF';face colour.
sCol='FF0000' //'FF0000';seconds colour.
mCol='FF8000' //'00FF00';minutes colour.
hCol='FFFF00' //'0000FF';hours colour.
ClockHeight=40;
ClockWidth=40;
ClockFromMouseY=0;
ClockFromMouseX=100;

//Alter nothing below! Alignments will be lost!

kann ich das irgendwie Firefox-kompatibel machen?
