Copy and Paste issues

[Erik Harrison]

I'm unsure if this is the place to put this, but if not, perhaps
someone could redirect me.

Copying to the clipboard is behaving like a PRIMARY selection. I don't
know when this behaviour started, and I only recently realized that it
wasn't a bug in my application.

Whenever a copy is performed in an application, that data is lost from
the clipboard as soon as the application closes. This happens across
apps, toolkits, and desktop environments. Is there a X.org
configuration that causes this issue?

Don't tell me it's been happening this way for 7 years now, and I just
now caught on. :-(
