can't got control without acceptation of client, yet...

Hello,

since some days, I don't understand why I can no more connect to a computer without have to request the control or that the client allow to show the screen.. 

Yet my settings allow full control to this computer . It's set on allow "integral" control.. Also this computer is added and assigned to my account.

I use the last version of teamviewer. The computer client is on windows 8. 

I have reinstall TV, but not solve it. 

Any idea ? 

Thanks

Mickael
