The CE15 1.03 app doesn't checkpoint and the main problem is, these are really long tasks so basically I can't finish any of them because when I shut down my pc, these tasks start over.
Turns out jobs for that app vary greatly in length. We'll revise to be sure that credit is granted for partial tasks. (In the meantime, will take this out of circulation.)
I have also wondred about this situation....Many Thanks for the info Matt!!
