Now the game doesn't hang on game over, but:
1) in the menu, if I select Setting, then local hi scores, fine I see my hi scores, but:
a) if I click on the button:
#1 the please wait banner comes under the hi score window
#2 it doesn't work, my hi score doesn't go on the global top20
b) if from the local hi score, I click menu then global top 20, the global 20 window comes under the local hi score so i can't see it.

2) the global hi score doesn't show the same as the net page: in ma global hi scores, I still see #5 tpd score 520 lvl1 date 2011-5-18...

Now I'll try with deleting all datas and reinstall the game

Edit: I can't find where are stored the user datas...
