Drag and Drop

[DuneWarrior]

Im sure its something completely simple im overlooking, but for the life of me i cant figure it out...

When you examine lets say an item, you supposedly can drag the icon in the resulting examine window and drop it in the chat window in order to link the item - ie link from something on the broker.

For the life of me i cant get the drag and drop to work .... any ideas as to what could be messing it up?
