CFForm inside CFWindow not submitting asynchronous

Hey everybody

I'm having an application, which is already running (within Mura CMS). Now I moved the application to another installation. And in there, a CFForm that runs inside a CFWindow doesn't submit asynchronous anymore. The action-url is opened in the browser-window (as a normal request).

CFIDE is mapped in IIS and ColdFusion Administrator and is available (otherwise, cfwindow and cfajaxproxy wouldn't work neither). Now it seems to me, that the problem lies within a newer version of Mura CMS and therefore my questions are:

• What are the possibilities to cause this error / misbehaviour?
• Where should I look?
• I checked the Doctype already and I'm also using CFAjaxImport.
• Neither Firebug nor Chrome are throwing any JS-Errors.

Thanks for any hint 🙂

Cheers

Boris

Ps: Is there an adverb "asynchronously"?
