Prodeo : Set hashtable size in Arena GUI

Hi,

I tryed to set it either by editing the .eng file and modufy the line
with w0 or w1 ... either in the UCI tab by the common hash table parameter.

please see on : http://jmonscavoir.free.fr/arena/capture_arena.png

i feel whatether i read on some internet site that Prodeo is better than
Spike (Prodeo is the best free engine in my point of view) but because
of small 3 Mb Hashtable in end of game, Prodeo lost sometime against
Spike (the "so call" number 1)

Thanks for your help
