Can not drag and drop User between Groups

Hi,

1. i have installed Gallery 3.09 on my Qnap 469Pro. It works very good. After Setup i create 2 Groups privat and public and i can drag and drop useres like written in the User Group Box. But now after 3 Days i create 5 new User and i can´t drag an drop any of them. Also i cant drag and drop the existing user ?? How can i fix it ?

2. i import Pics with iPhoto plugin for Gallery3. When i do so the Album Name in /VAR changes from Name to Number. The pics are all ok and i can view them.. but the right directory Name would be nice. How can i fix it ? Rename and run Maintance don´t help the pics then broken. Maintance without rename don´t changes anything.

Thank you for your help.
