Ripple Edit with frozen tracks

[Sven]

 I use Ripple Edit a lot to copy/paste sections of my songs and create new arrangements.  I looked briefly at the Cakewalk Arranger option but thought my method using Ripple Edit worked better and quicker for my needs.

I often have frozen tracks of MIDI synth track parts and I believe I've seen Ripple Edit  faithfully copy/paste both the MIDI and the analog frozen parts to the new sections.  But occasionally I see the MIDI copied but not the frozen analog track.  It's no big deal to unfreeze/refreeze those tracks to get the results I want but I'm curious why it doesn't always work the way I would like it to.  Is there an option I'm not setting correctly?  

Thanks.
