    I have a new crash that happens in the Scheduler javascript code that I'm not sure how to begin debugging.  Are there suggestions that you guys use that you could share with me?

    This is the type of error that shows in the IE 8 error window: 
    Webpage error details 
    User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2)

    Try using Firefox in combination with the plugin "Firebug". This gives you debug options for javascript. It even supports breaklines and such.

    Unfortunately, I believe this particular crash is beyond firebug.  I have downloaded the source to the 2009.3.1103 build and have built it in debug following the instructions found the in the instructions.pdf included with the source, but when I hit the exception I still see all the javascript compressed into one line like the release version.

    Is there an extra step to get VS to use the source js files?

    I think the best thing to do would be to describe exactly what you are trying to do, perhaps there's an issue with your implementation that is causing this javascript error to be thrown.

    On the same note as Datamex had you can also try out Telerik's new JustCode tool, it's pretty nifty and helps out a lot with javascript :)

    I'm seeing this javascript error as well from time to time. Often in IE6.
    I've just added a new appointment to my schedule and switched to week view or day view. Switching back to month view gives me this error in some compressed telerik javascript file.

    has anyone made any headway with this? What are some things that would cause this issue?
