First thanks again for helping me,
In the first picture you can see my desktop and the toolbar, here I have opened Mozzilla and Paint.
In the second picture I have opened the New folder (in the previous picture was close) and you can see that the icon is already changed.
In the third I have opened another folder with different icon (Music) but still the Icon 3D is here.. (usually I see 2 different icon, the music icon and the folder icon)
The fourth is when I right click on the 3D icon in the toolbar, the only thing new is that it say:"Esempi foto 3d" that mean "3d pictures examples", it came when I installed the program.
I only use roxio to burn cds to listen in my car, I never used or opened any other program that comes with ROXIO Creator PRO 2012.
You asked me for association, if I undestood you mean with what program I open music or movies, the music with Windous Media Player, and the movies with Home Classic Cinema, I don t think this is the problem because this happen only if I open a folder not a file!
Hope my english is not so bad
