Klipper running or not doesn't matter - its configuration affects KClipboard, used
by all apps; so make sure it's set to "separate selection and clipboard".

What you describe sounds like a bug in KHTML I fixed recently, where
the text selection code would sometimes fail - and therefore didn't copy
the selection. How uptodate is your khtml? Does updating it help?

I also have a further patch to improve text selection, but it got no review yet,
except "it looks messy" by Dirk :). It does, but not that much. The point is to detect
when the mouse is "above everything" (in the top margin) or "below everything" (in the
unused area below the HTML). See attachment. I doubt it helps for your specific
problem though, unless it's about selecting the very beginning or very end of
the message.
