alert(/[^0]/.test(""));

Those 2 lines of JavaScript code should produce 2 dialog boxes that both say
"false", but the first line erroneously produces "true". 
There is a bug in the regular expression processing part of the implimentation
of JavaScript in Netscape 4.72.
I've tried this on HP-UX & on WinNT versions of Netscape with the exact
same result.
Bugs in 4.72 need to go via 

http://help.netscape.com/forms/bug-client.html 

(I forwarded this one already)

for what it's worth - this bug is fixed in Mozilla.
