Not sure if anyone experience this but I found if you use Stellarium Scope with Windows 10 do not keep it running very long or you'll get a notification that you're running low on memory. I found it takes about 2 hours then you'll notice the system appears to be sluggish and a short time after a pop up will appear about low memory. I traced it back to Stellarium Scope, must be some type of memory leak. Once I close Stellarium Scope the system returns to normal operation.
