On old version of screen installed on Centos 5.5, for example this ....

$ screen --version
Screen version 4.00.03 (FAU) 23-Oct-06
$ rpm -q screen
screen-4.0.3-4.el5

do not clean terminal copy/paste buffer when I run a new screen or I reuse a previous screen ... and this is good!

But the subsequent versions to last current version ...

$ screen --version
Screen version 4.06.02 (GNU) 23-Oct-17
$ rpm -q screen
screen-4.6.2-1.fc27.x86_64

clean the terminal copy/paste buffer when I run new screen session o I reuse a previous suspend screen session

When I'm inside a screen session and I select with mouse some text, then copy it with right click into buffer, when I exit from screen and return into terminal session, the copy/paste buffer is not clean and I can paste the previous copy text via right click or press the middle mouse button.

But if I copy some text previous to run a screen, then run a new screen or reuse a suspend screen, when I'm inside the screen the copy buffer is empty and I do no t can paste it in any way.

It's possible disable this "clean copy buffer feature" of the screen?

Many thanks
