autocompleteextender and Access Denied

[riazs]

Guys,

I don't know if I'm in the correct forum... anyway here goes:
Does anyone else get the Access Denied error when typing text into a text box which is linked to an AutoCompleteExt ender.


the javascript breaks on:
this._xmlHttpRe quest.open(verb , this._webReques t.getResolvedUr l(), true );



I’ve listed my html for the autocompleteext ender
