There's something wrong with Registry Monitor's Compare function.
Build 2.0.0.966
(maybe in previous builds also - didn't check this function previously)
I selected a Snapshot (made with default settings) > Compare (with default settings) > Start
The little wheel (hourglass) is spinning, but in the message box "Working. This might take a while. Please wait..." the values of "Keys analyzed" and "Values analayzed" keep staying both on "0".
The memory use of jv16PT.exe *32 is ca 177.000 kB (normally when starting PowerTools ca 55.000 kB) and the CPU usage 0% - 1%.
Obviously the compare process isn't working and after 10 miniutes I aborted the operation. Nothing happened at all during "Comparing".
It's repeatable: it tried it several times without any success.
