On my P233MMX with 98304 KB hash tables, Fritz 5.01 sticks with Ra3 all the time
(from the very first second) and NEVER (I let it analyze 5 minutes) changes to
Re3 (eval for Ra3 is +3 for black after 0 seconds, +5.25 for black after 5
seconds).

What's the date and file size of your Fritz 5 engine?
How much hash tables did you use?
