Unable to drag and drop

We installed, uninstalled, repaired and we still are not able to drag and drop files into CorelDraw pages. For example and jpg or eps from Explorer cannot be dragged into a page in Corel. All we get is the UNAVAILABLE icon.

This is very inconvenient, when we did a live support months ago, we were told that they would investigate it further and get back to us. We do date have not heard any more on the subject.
