[Evolution] How to copy/cut from the body of an email

[Graham Murray <gmurray webwayone co uk>]

Using Evolution 3.2.3 under gnome on Linux. Is there any way of copying
arbitrary text from the body of a received email. When I try to use the
normal X mechanism of left-click and  drag the mouse, as soon as I
left-click it immediately selects lots of text (often from the start of
the current or previous paragraph, but not always).
