I've got a function that is called when a form is submitted. This function is likely to produce errors so I have used a try...catch block. However this only seems to work in MSIE and not in Netscape 4.75. I've tried using onError but because you have to return true in the error handling function the page reloads. Is there either another error handling function in Netscape or a way to return false from the error handling function?
