We are currently having issues with some javascript functions in our web applications. We began having issues as soon as our operating system switched from Windows NT to Windows 2000. We do not seem to have this problem W2K when combined with IE5.5, but many of our users now have the W2K/Netscape combination. Does anybody know where we can look to find information about Javascript compatibility with operating systems? FYI..one major problem that we are having is with pop up windows if anyone else has had similar issues, please contact us?
