To Uri: "un-stability" in Movei analysis

[Jouni]

I have often seen one thing in Movei analysis, that is weird. Movei often "vibrates" between 2 or even 3 best moves. Example:

[D]rr5k/4b1p1/5pPp/1N2nP2/8/4q3/1PQR3P/1K1R1B2 b - -

Is this bug or feature? BTW Uri Movei is now good in all test suites I have
tried so far, great!
