I'm developing some custom pieces for a Sitefinity site as custom user controls that are added to Sitefinity pages. I have a modal popup extender from the AJAX control toolkit that works in my dev environment, on the live site in an empty template, but not in the actual templates they need to use. It's using the toolkit ScriptManager
It looks to me like something coming from ScriptResource.axd might be in conflict with the script manager I'm using but I have no idea how to track this down in Sitefinity.
I'm not getting any errors when my AJAX isn't working, just that my hidden modal window is always visible instead of being shown/hidden on click.
Any information that could help me track down the cause would be helpful.
