does you web root still have aspnet_client folder with the validtion js file
? i have heard of it messing postbacks
extracts from a channel9.msdn.com
---------------------------------
I was having similar problems with events not firing. There could be a
couple things going on here, but I got it solved by doing the following:
1) Run the command: aspnet_regiis -c
This should take the new javascript libraries from the .NET framework and
put them in your C:\inetpub\wwwroot\ directory.
2) Restart IIS (at least I did)
3) Make sure all your web applications are using the new aspnet_client
directories. I was running into an issue where an application was using the
old JavaScript libraries because they had been copied into an application
directory.
As a note, I am running IIS 6.0, XP with SP2.
Good luck! This was a pretty frustrating problem; hopefully this will save
some folks a lot of pain.

hope that helps
