I don't know if one of the parameters is to blame or all. I just used them for power save mode, at least that's what they said on the internet. Anyway, now I don't get the error.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
