ok thank you for your answer
I found two other problems not very serious:
the weather widget can't give me my exact position, even when I manually refresh it always find myself in a city next to my position at nearly 15km
and next to my network signal reception it shows me only the symbol "R", and do not tell me if I + 3g, 3g, 2g.
may be, the problem comes from the fact that I am in France?
but i love this rom, very fluid, very simple, very light, this is what i like, great jobs!!!
Sorry for my bad English i'm french...
