[Studio] Try to package a Studio fragment

[laurent cop]

Hello, 

I have made a fragment (add popup menu) in studio. So I try to make a fragment 
without anything from studio.rcp (as a host) as it contains the Application. 

Under eclipse, my fragment works fine.

After when I want to package  as a product, I loose all perspectives :-(  give 
me something like close all perspective. 

Any help welcomed.

       Thanks
