Dragging

Hopefully this question will have an easier answer than my last. I am using PocketCloud Pro on my Droid Razer Maxx, connected to a Motorola Lapdock 500 Pro. From there, I am connecting via RDP to a Windows XP Pro computer.

I see no way to drag anything. If for example I have a window on the remote desktop that is somewhere between minimized and maximized and I want to drag it off to the side, how do I do this?

The scrolling feature also works on and off, but it does seem to work with my wireless mouse connected to the lapdock.

Thanks
