>>Have you included memory management via SYS(3050) / SYS(1104)? Might you have a memory leak that's only manifesting itself after a very long period of time?

Hey Al. Intersting idea. After each report is run, I will print SYS(1016) to see if the amount of memory is climbing.

Just curious, what makes you think that this could be a memory issue? Clicking on the window shouldn't revive the app if it was memory problem, should it?
