Yes, I have noticed that after I open some menu options and then close them, the memory usage remains higher than it was before I did that.
However, as BrianF7408 says above, the memory leak is still there even if I don’t do anything. 99% of the time, WD is running headless with TV switched off and no mouse enabled. And yet it still consumes memory at the rate of about 145MB per hour, as per the figures I sent you.
