Drag and Drop of external objects in Webdynpro Applications

Hi Gurus,

in some systems it is possible to drop external objects (i. e. Outlook mails, text snippets) from other applications onto webdynpro applications, in other systems it is not. I have one system in which I want to enable dropping emails onto wd.

Does anyone of you know how to change that property?

Thanks a lot in advance

Bernhard
