Offline Tasks pop-up is stuck?

The logic for the Offline Time works like this:

If there is no keyboard or mouse activity for 5 minutes, display the Offline Time dialog and continue updating the "Total Time Elapsed" until there is some sort of keyboard or mouse event detected.

Once activity has been detected the "Total Time Elapsed" counter freezes, and will not restart regardless of how long you let the computer sit. This is somewhat on purpose, but behavior that we may change in the future based on feedback - we've argued about it internally ;)

Once you select an Offline Time button and dismiss the Offline Time dialog, all of the counters reset and the next time a 5 minute "idle" is detected it will re-display the Offline Time dialog with new values.

If your Offline Time is never counting a "Total Time Elapsed" of more than 15 minutes, and it is consistently 15 minutes, then I would hazard a guess that you have another application or process that is sending a keyboard or mouse event every 15 minutes.

In the past, we have seen some screen savers that do this, and there are third party utilities that try to prevent the computer from sleeping by simulating a non-intrusive keypress (like the shift key) periodically.

Let me know if that helps explain what is going on with your system. It is certainly possible we've got a counter bug in there somewhere!

Thank you

Thanks for the additional information Balaji! That helps me focus where to look for the problem.
