I can't get window.open to work right with Mozilla even though it works fine with IE (Windows XP) and Epiphany (X Windows). By "working right" I mean that the URL I call with window.open will popup on the working browsers. On Mozilla the new URL appears in the same browser, removing the page that executed window.open.
The following code replicates the problem I described. The purpose of the code is to open a popup when I enter the <Enter> key inside the text field:
var keyCode = evnt.keyCode ? evnt.keyCode : evnt.which ? evnt.which : evnt.charCode;
if(keyCode == 13)
<form action=index.php method=post>
<input type=text name=myval onkeypress="return handleKeyPress(event);">
