Dear Maintainer,

   * What led up to the situation?
This problem seems to have become reproducible recently.

Once the machime boots up, I open the epiphany-browser app,
and this opens one or more web pages.
I then open Libreoffice, and open a text page.

I return to epiphany. I use the mouse to highlight the text
of the URL, left-click, swipe right to left.

A drop down menu appears: cut; copy; paste; and delete.

The first time I run this procedure, it follows the normal
process: I select copy, and then paste the URL text into
a libreoffice txt page. I then highlight some text in the
browser page, and paste that into the libreoffice txt page.
I save the libreoffice txt page.

With that done, I close the browser page, which automatically
shows the next web page.

The second time I run the above procedure, I find that
not only am I unable to select 'copy' on the drop down menu,
but the keyboard is inaccessible, the mouse buttons do not
function, and the clock does not show  an update to its time.

I usually depress the start button momentarily to get the
machine to reboot.

I'll guess that the chances of this happening are now 50:50.

I just tried again. This time it locked up before the
drop down menu appeared.
