I think I solved my own problem after "digging" through the documentation.
The solution was to set the scope attribute for the creator element in
dwr.xml to "script". This eliminated the bug in Internet Explorer 6.

Although I didn't find a bug in the code, I have found a bug in the
documentation. The link below describes only the four following scope
attributes: "application", "session", "request" and "page".

http://getahead.org/dwr/server/dwrxml/creators

I found documentation on the "script" attribute in the changelog located
here:

http://getahead.org/dwr/changelog/dwr20

Please update the documentation on creators to reflect this scope attribute
so that others will not have to chase their tail :)

Thank you,
James Mortensen
