What I meant could give some difference is:
Fritz lower the priority of engines to 'below normal'. This is true for Shredder
UCI, and also for Thinker if you remove the priority line. Eg. they get the same
priority. When you add the Priority=normal you force thinker to run with a
higher priority than Shredder.

In Shredder Classic (and Arena) all engines are running with 'normal' priority
so with 'Priority=normal' you only force it to use the priority it would use in
any case.

The thought behind the 'Priority' switch is to give a nicer, more userfriendly,
gui when analyzing with gui's that don't lower the priority eg. Shredder
Classic/Chess Assistant etc.
You can surf on the net, work with Word, do some programming etc. all when you
have the engine to analyze a position, and the response from all these program
would be like you didn't have any engine analyzing in the background. The
analysis itself wouldn't be hurt to much, maybe 10 sec. slower for a 10 minutes
analysis.
