Hi, for some reason, my Feature Tree has decided to turn upside down.  I usually have "Favorites, History, Sensors, Design Binder....Front, Right and Top planes on top and my assemblies and parts below that followed by Linear and Mirrored patterns.  I've attached what it looks like.  I've tried dragging and dropping the assemblies below and tried dragging and dropping the Favorites, History, etc above to no avail.  I've also tried doing a pack and go but that didn't work either.  This is the only assembly this has happened on.  Has anyone else experienced this?  Is there a way to fix it?  Any help would be much appreciated.

Thanks,

Verne
