Zara Studio 3

Hi...I just purchased Zara Studio 3 after using Zara Radio 1.6 (free version). I have a Dell Precision T5400 computer with a 500GB SSA, 4 GB RAM, and a 3 GB processor. The display tends to lock up but the audio still plays. But if the display is locked up at the end of the song, it may take 5 or 6 seconds, maybe more, before the next event is triggered. Any ideas on how to mitigate this?
We have Zara Studio 3 also and wanted to know more about the Automatic Gain Control (AGC). I see 3 options but the manual doesn't say much about the difference.
Also we have on occasion lost time with Windows 10 and it really messed up the Events and playlist. Anyone out there have a better idea than running a 3rd party app that checks time and adjusts it thru the day or manually reboot? We've heard its a Win 10 issue.
