Ok .NET framework had a recent patch, and it broke many of our web sites. All imageButtons just don’t do anything.
The patch damaged the client scripts in aspnet_client folder. We need to update them properly.
Run the following command lines
Option -ea will remove all scripts in all aspnet_client folder. -c will install the scripts again.
But, sometimes it complains about insufficent Administrator Privileges. This was really tough one to figure out. Some scripts in aspnet_client folder were somehow marked READONLY (might be because one of our developer added aspnet_client folder into sourcesafe and it marked them as readonly). Manually deleting those script folder did the trick in this case.
