Re: JavaScript problem with Netscape

Webnet,

Thanks to those of you who responded to my post. I think this problem
might be documented as bug 65581 at:
http://bugzilla.mozilla.org/show_bug.cgi?id=65581

Given that this appears to be fixed in NN7.2 - Gecko/20040804 (thanks
Bruce) and that the above report indicates that some earlier versions of
Netscape may actually crash or hang as a result of this bug, I think our
best option is going to be to alter our javascript to skip the focus()
when the Netscape browser is at a version less than 7.2.

One other note: this same javascript works fine when called from the
body onload handler. It seems like most people call focus() from onload,
so that may explain why we aren't running into this problem more frequently.
