I'm not sure what you mean? Can there be problems? How I use/play it: I move around either only with the mouse or I move around first and then click where I want to click. But maybe I'm just not seeing it and I can fix it!
e.g. Keep clicking on castle to produce gold can be replaced by: A. hover on castle to produce gold; or B. click castle once to begin produce gold, click sawmill to switch to wood.
