Sometimes during a battle I will get to a point where I will select a unit and tell him to attack/move/cast, I will move the pointer where I want that action to take place and r-click. Nothing will happen. USUALLY if I repeat the right click several times the unit will get hte hint and do what I tell it. Sometimes however I will remain unable to issue orders. WHen this happens, I become unable to select anyother unit or issue any commands at all. Even the end turn button stops working.
Oddly enough the only button on the whole screen that continues to work is the auto-resolve battle button.
Have others had this issue or is it my marginal hardware?
