Hash size makes a little difference, but not a lot. The slowdown I'm experiencing with the Shredder Classic GUI is something more fundamental. It is probably an incompatibility with the Windows XP Home operating system, either at the coding level or during compilation. How else can you explain that it takes a minute or two to simply open another program (for example, Outlook Express) while a chess engine (usually Shredder 8) is running in the Classic GUI? This problem does not happen with the Shredder 8 CB/native GUI. Another possibility that comes to mind is that there's a difference between my Athlon XP 2400+ 2.0GHz processor and other processors such as Pentium 4's with hyperthreading. What works well on the latter may not work correctly on the former. So if people are writing and testing code on hyperthreaded processors, they're leaving the rest of us behind. Just an idea. I don't know. Thanks for the tip about rightclicking processes in the Task Manager to change their priorities. I wasn't aware of that operation, and will give it a try. However I uninstalled the Classic GUIs, thinking I would never attempt to use them again, so will have to wait til I have some free computer time to reinstall and test them again. I've tried both the Classic 6 and new Shredder Classic GUI's, and they seem the same in these regards. WP
