Hi gamers,

Not really that I know off (you could check AUM magazine ofcourse, see left bar of this site). Besides that you could check how long a panel (which contains the button object) is visible and store that somewhere. As for 'button click time', I dont entirely get what you mean with this but maybe store the time in your button function increase the time (in a loop) till the user released the left mouse button (mouse_left).
What is it your are trying to accomplish?

Also you use the variable 'total_secs' to save duration of total use of the application.
