I had this problems sometimes but now I just turn the camera to the top if my move is really important. Maybe it will help to activate "show grid" option?
Maybe it whould help if a selected unit will automatically show it's trail and highlight it's destination square befor you have to click. It would additionally be nice if you will see the duration the unit will walk in turns in the preview. This would be a User Interface modification but it works for me with the top view.
