[2005] I have the IE client error: AJAXControlToolkit" is undefined only on my machine

Hi,
I have ajax controls and toolkit controls on my pages.
Every thing was working fine on both my dev machine and on the servers. All of a sudden, (I don t remember what changed exactly), the stuff works locally on the server, and also works from other client machines.

But on my dev machine I get the js client error:
'AJAXControlToolkit' is undefined

Any idea why I have that error only on my machine and only in IE not in FireFox?

Muchas gracias.

actually, not totally true, I checked more PCs and the problem occurs in many other PCs and it only works from 2 computers, so we definitely have a problem in many PCs.

Other thing, I was a bit playing mixing the AjaxControltoolkit version 10618 and the last one released on September 2007. I wonder if that s what s causing the PB.

Merci :)

I created new application all over and copied the files and every things seems to work well and fine. Thanks for inspiring me :)
