Some additional feedback: just FYI, the past two days the miner has shut down overnight and requires a full shutdown and restart to resume. I am running the latest version, Windows 10, two dual-xeon boxes, CPU only, mining XMR...
EDIT/UPDATE: It just happened again. It stopped reporting hashrate but was still using my CPUs as if it were running at 100%. Live page showed no hashrate running for my account. Deleting app for now. Need better assurance that my hashrate is not being lost and/or hijacked and a more detailed explanation why it must be run in admin mode.
I reported this a few days ago. I was told that as your account ages, the status page starts updating less frequently (like 1-2 hours). It freaked me out as well. They say they're working on improving it.
