Hello,

 In the explorer of my mobile-pocket device

I can read files (take it and bring it to my computer from the mobile)
I can delete files on the mobile

BUT I can not send a file to the mobile

 I was abble to do this before. But now, when i try to drop a file in
the explorer, this does not work anymore :  i take a file, and when the
mouse comes up to the mobile folder (the explorer) then the mouse's icon
becomes a "forbiden icon" (black circle with slash ) and the drop is
impossible. No error message, but nothing happend.

 i need a little help to send files again to my device.
Thank you. (note: i try a hard reset of the device, but no change)
