Script for executable idle timer

[Magicgate Software - Skip Kimpel]

I have an executable that needs to monitor if it has been sitting idle for
an hour.  If so, it needs to quit.

What is a quick, un-intrusive way of doing this?  Maybe even display an
answer dialog box to continue the "session" and giving them 10 seconds to
respond, after which it would shut the executable down as previously
described.

Quite a bit of what I finding in the forums seems to be mobile based but no
clear cut answers when it comes to standalone executable.

Your insight is always appreciated!
