We have an ASP.NET application and when running on client site they often get null reference Javascript errors. As with all these errors the information IE6 displays is less than helpful. But the problem is as soon as I install IE script debugger and try and debug a bit more the error becomes non-reproducible.When script debugger is not installed then the error occurs again. Are there any other tools that could be helpful for javascript debugging on client site. The error is also not produced with IE7 or Firefox.
