word learning in WM6

[walways]

Would anybody know how to tweak the number of remembered words (not suggested words) in Word Mobile ? I write my stuff on PPC (iPAQ 214, Dutch, WM6) and after a while it 'forgets' the 'older' words I used. In my opinion that could be because there is in aregistry setting that rules over the maximum space for words, because of which after a while the old ones get dumped while new ones get entered (new in, old out). Has anybody an idea how to change this behavior, perhaps a registry tweak?
