it's christmas and I got a new iPod touch.
Everything is fine, well nearly everything.

Dropbox synchronization will not work anymore from and to the new device.
After searching a while I found the reason.
All of the old devices (the computer, and old iPod touch and an Android mobile phone) store thre data inside a directory structure starting
with
...Flashcards Deluxe/_Sync/...
The new iPod touch prefers by any unknown reason
...Apps/Flashcards Deluxe/_Sync/...
In both directories everything is fine for the corresponding platforms. I crawled through the new device for the location of this
additional "Apps", so far without result.
I believe, finally it's trivial.
