Windows Clipboard is cleared when the client is closed

Hi,
when I copy something from the Jamulus client (e.g., an IP address) with CTRL+C and close the application, it is deleted from the Windows clipboard. I think this is not the expected behavior. At least for me it was annoying, because usually I copy something, then close the app, then try to paste it, it doesn't work so I think I didn't copy it correctly, go back etc. etc.
So for me the expected behavior would be that copied content stays in the clipboard, this is how other Windows programs behave.

Start by reproducing the issue in the Windows Jamulus client: copy an IP address with CTRL+C, close the application, and try to paste it. Locate the client code responsible for Windows clipboard handling and verify that copied content remains available after shutdown. Done means the copied text can still be pasted after the client closes.
