If I work on multiple screens and have multiple applications, how will Prohance capture my time?

Prohance captures the time spent on active window irrespective of the number of screens and applications you are on. Hence, details of applications in the background are not captured. Also, if you are using multiple screens or multiple systems at the same time, ProHance will only capture information of time on the window (active window which is in focus) and system on which you are actively working at that time.
