Can someone show me (an example) how create an effective error trap that would work both in JavaScript 1.1 (Netscape 3.x+ IE-4.x+) and JScript - both of these support onError. [say for Example: something that would pop up my own<BR>alert() message instead of the browser&#039s)<BR><BR>I&#039ve tried using different combinations on:<BR>window.onError<BR>but i can&#039t seem to get it right. (I&#039m not even sure wether to use onError as an event, method or propety.)<BR><BR>Can anyone Help?!<BR><BR>Thanking everyone in advance,<BR>Aaron
