excuse my elementary English, I installed all versions after 1.5.1.16.17,
but in all I had the same problem, so I went back to 1.5.1.16.17 that works perfectly.
In particular, this happens: two of the three accounts are updated simultaneously,
immediately after you update the third. Subsequently, are updated only the first
two and the third most ever.
Until version 1.5.1.16.17 accounts are updated one at a time, the first, then the
second and then the third and so it works properly.
Thank You
