Hi
Sorry for this i've never seen the bug before. I think it's because i put 'backup()' in the initialize function.
So you can replace
code:
function OnEvent_Initialize(MessengerStart){
backup();
}
by
code:
function OnEvent_SigninReady(Email){
backup();
}
The error disappear for me. I'll send the update to patchou but this error is not very important, the script works perfectly.
Thank you for told me about this.
