You'll guess from the question that I don't often use Free Commander

I just can't find a way of adding a file/folder from my Desktop into Free Commander when it's open but showing another folder (not desktop)
Just now, I tried copying the folder and once in FC and the folder I wanted to add it too, I right clicked with my mouse but the Windows dialogue box I normally get flashes and then disappears.
There must be an easy way?
Also, is it a bug that the Windows Explorer window I normally use does not work in FC?
Thanks
