When I select text in Mozilla Firebird .6, a
middle-click does not paste it into rxvt. It does
correctly paste into xterm.
Copying text from rxvt and pasting it into Mozilla
Firebird works fine.
I'm using the Fedora Linux build of Firebird
(MozillaFirebird-0.6-0.fdr.4.rh90) and rxvt-2.7.6-4.
Note: I just built rxvt-2.7.10 from sourceforge, and
the problem is still present in that release.
