When I exit C6, why does it clear my copy/paste clipboard?

Hello!

I’ve been writting stuff in Microsoft Word while I’ve been using Cubase 6.0.4 and I’ve noticed that when I exit Cubase 6 it automatically clears my copy/paste clipboard. I am sure of this and I can confirm that this happens even if there is NO Cubase-centric information in the clipboard.

Why does it do this?
I’ve posted this thread because I just got tired of loosing information because Cubase exits.

Thanks!
