Comment 6 for bug 38431

Thanks for your bug. I'm rejecting it since it has nothing to do with gnome-panel and that's not a bug. If you want to open a specification on launchpad or the wiki about that you are welcome

Some notes about that though:
- gnome-settings-daemon has a clipboard manager
- apps have to use it, you can try with gedit by example. Open it, type some text, use Ctrl-C, close gedit, use Ctrl-V to some other application or reopen gedit and hit ctrl-V the text is copied
- a clipboard applet similar to klipper would be nice but that's a request for a new software, not a bug

The select,middle click copy might not use the clipboard though as explained by the bug Daniel pointed that's the way xorg clipboard management is done
