Dear Sirs,
 
I am trying to create a workflow from scratch although it has been impossible for me.
The simple problem is that I cannot move the boxes through the canvas.
Each time I add a new box it is sent to the same position in the canvas, all the boxes overlap and I am not able to move or connect them.
According to the screencast "Workflow from scratch" when you put the cursor on the top of each box, a pam icon appears and you are then able to move the boxes representing both, input datasets and tools. However, when I try to do so, a cross icon instead of a pam icon appears and it does not allow me to move to boxes.
 
Any help in this topic is welcome.
 
Yours Faithfully,
