Hi,

I have windows 7 64 bit.
I have windows live messenger.
When i chat with my brother in the messenger i dont have the view history option/button/click...

I went to the long directory on the hard disk according to the Options>History in my messenger and saw there all the history files .
But i cant view them through the messenger why the option is gone ?!

How can i view now this files through the messenger ?
