data at the root level is invalid problem

[jm]

I get "data at the root level is invalid." I have changed security
for the IUSR_xx to be in the adminstrators (tried anonymous access);
changed all the file security I could; tried virtual directories and
file paths. I have googled and googled. Any ideas why it cannot load
this file? It is not the files, I believe, I didn't make them they
are from 4guysfromrolla. Any ideas what is causing this bug? Thanks
for any help.

I found that the only reason this failed was because:

autoeventwireup="false"

was there. I removed the entire line and it worked. Setting the
value to "true" will also cause it to work.

Is this a bug or by design?
