Problem with debugger

Hi everyone.

It's the first time that I'm debugging a Wii game, Fragile, so I don't know if it's normal. But when I put a Write Memory Check in an address, the emulation breaks after all the data has written into memory, even at the addresses after the Memory Check. I want that the emulation breaks just before writing into memory. How can I do that?

Thanks

(Sorry for my bad english)
