double tap and hold does not drag windows

I bought the full version of your iRemoteDesktop app last night. My only problem is that when i double tap and hold down on the second tap and move my finger, it does not drag windows around. It moves the cursor with my finger, but the left mouse button is not pressed down, so it does not grab anything.
I can move objects by opening the trackpad and holding the left mouse button there, but I would prefer to be able to double tap and hold to drag things. I am running on an iPad 2 with iOS 5.
