Writing New Control - WebResource Url Throwing Exception

Hey Everyone,

I'm having a really hard time with this one. I recently upgraded to lateest control toolkit, and now i can't use my custom controls. I get the dreaded unrecognized tag error.

When I try to load the webresource.axd url for the javascript, I'm getting the following error:

WebResource.axd?d=_IYF6c389WdEZP8BREten0VCyRTYFXUFn9GR9MRXP-aoOJ5cYUZwsxAz4rdBOPaz6CoHQyUbH48-Kn0gv5WhhCj2yI8nUNAt-hz-wRrJAwI76fBROssmxDJplsNW85vw0&t=632907313964152042

any ideas?For some reason, the Atlas Control Extender template doesn't make the Behavior.js an embedded resource. Change that in the properties pane and rebuild.
yeah, i saw that in the FAQ, and made sure (and double sure) that it was marked as an embedded resource. and it looks like it is, because i am seeing the resource in the source. it's when the browser tries to read the resource that .NET is throwing that funky WebResourceCompressionModule error...
So using a tool like Fiddler, the js file is being sent across?? Hmmm.
I actually saw this yesterday when I was doing some work but (unfortunately) I didn't ever figure it out, mostly because it kind of magically went a way. I think I rebuilt everything clean and it started working.
