Your response is not totally accurate.  I only work on my computer.  I am never away from it for more than 15 minutes when I am clocked in working, so my mouse, keyboard, etc. are active the whole time I am clocked in, yet I still have to log in again to clock out when I am finished no matter how long I work. 

Most of my computer stuff is done in the same browser that has the QB timecard on it and I am not in any other QB applications.

When I work only an hour or so it is logged in but if I work any longer than that is has timed out.

Any suggestions?
