Currently it is not possible to copy an image from Connections Wiki to any other application. In this special case a user wants to copy/paste an image from a Wiki to MS-Word. It does not work.
I was running a test with IC 6.0 CR4 and IC 6.0 CR5 which used textbox.io and CKEditor. We tried also the new Tiny MCE Editor. In any constellation copy/paste does not work.
