Running emacs -q -no-site-file under X-Windows, if I do
control-mouse-1 to pop up the buffer menu (runs the command
mouse-buffer-menu) and select a buffer from the list, then Emacs DOES
NOT switch to the buffer when the mouse button is released.  However,
if I do control-mouse-1 and release CONTROL before mouse-1 then the
buffer switch occurs as expected.

Similarly, if I use mouse-1 to select some text in a fundamental-mode
buffer and then use control-mouse-3 to pop up the Edit menu, selecting
Cut an releasing mouse-3 has no effect, but if I release CONTROL
before mouse-3 then the command works as expected.

This problem does not occur if Emacs is built with the Lucid toolkit.

I an running Emacs on a Solaris workstation from a remote
X-Workstation - a Windoze-2000 Pro PC running Hummingbird Exceed.

Just tried using the Sun workstation's local display, mouse and
keyboard.  The same problem occurs.

My guess is that the modified mouse-up event is being ignored.
