Oops, I didn't understand that GC free the memory for itself, and not for  
the system ^_^

In your case, can "delete" replace "GC.free" ?
All in all, "delete" works  on mine : the "old" memory space can be re-use  
by another array allocation.

But why GC.minimize doesn't free the memory to the system ? Does it come  
 from Windows Vista ? Or is it the wrong command ?
