AutoPostBack causes script error

[Coach]

I have a dropdown list and 2 radio button groups that cause a script error
when they are attempting to post back. The error for all 3 is an Object
expected error.

The page works fine from my development machine and from a development
server. The only machine I have this problem with is the live environment.

Any ideas would be greatly appreciated.

I have the same problem with radio button group, but it only causes the
scripting error if done from a web control, ie it doesn't cause trouble if
buttons are embedded directly into a web form. I get the feeling that problem
has to do with the way the name of a control is modified if it is part of a
web control, something like webcontrol_name:button_name.

is this a known bug? Any way to work around it?
Thanks!
