In the attached game, there is a blunder, move 28...Bh6 because lost position becomes draw - perpetual check, but it is undetected by Aquarium 2011 build 490. Another blunder is 32.Qf5+, better is 32.Qe7+ or 32.Qe4+ because it remains draw - perpetual check. It remains undetected in Find blunders or game analysis mode, regardless settings - it goes too quickly through these moves and assigns evaluation -7.0 and does not analyses it further, probably because no significant difference in evaluation. But when using analyzing current position, it spots immediately draw. After that manual iteration (without clearing hash) Find blunders and Game analysis works fine. Using Stockfish 2.2.2 64bit and Komodo64 3. Any idea if there is a possibility to fine tune settings in Aquarium to detect these blunders properly?

it´s merely an undetected setting of Game Analysis.
Look at your settings and change Variation length to 17 or higher or use manual setting tab and adjust "AND plies" 17 or higher and even a 2 minutes game analysis will detect that blunders at once and assign "??" to Bh6 and Qf5
Kind regards,

Thanks for attempt, but I am afraid it does not work. I set even 21, tried both variation length or manual tab.
Can´t believe that.
See attachement of screenshots of analysis with Rybka 4.1 and 2minutes. I tried with notebook and stand alone pc, it worked.

Astonishing....
I can´t explain that phenomenon, maybe you used stockfish in single core mode, but i used Rybka with dual core (notebook) and 6 core (PC).
Now I made a test with Stockfish 1.7 w32 in single core mode with Aquarium 4.07 (a fresh setup, before Aquarium 2011 tested), but the blunders are exposed immediatedly. Testing with stockfish 2.2.1 and Aquarium 2011 give correct results.
Last question: Do you use a netbook or very old PC?
Otherwise I have to admit that I can´t help you.
Sorry,

Notebook i5@2.5GHz. And when I am in infinite analysis mode, it spots blunders immediately as I move on these moves. Problem is in game analysis mode and Blunder check mode. No idea what is going on....
