Hello,

It appears that the latest xterm-261-1 package still exhibits the 
dysfunctional scrollbar behavior
(tested with Xorg server 1.8.0-1).  The scroll handle starts at the top 
of the slider and never
moves.  And, when any mouse button action is issued in the scroll bar 
area, the entire bar (full
height of the xterm window) becomes shaded.  While scrolling is still 
possible, it is not the
expected, nor desired, behavior.  This was true of the previous 260-1 
package (and a few prior)
as well.

It appears that an attempted workaround/solution was incorporated in the 
"xterm-261-1.cygport"
file (provided with the src used to build this release) by adding the 
"--disable-narrowproto" option.
However, the "--disable-imake" option also appears to be required to 
resolve this errant behavior.

To resolve this issue, I rebuilt my xterm from the xterm-261-1 release 
src as follows (detailed for clarity):
(note: lines prefixed with "[user@node] >" denotes a cygwin bash shell 
command-line operation)

 - installed the src (via cygwin setup)
 - [user@node] > mkdir ~/xterm-build
 - [user@node] > cd ~/xterm-build
 - [user@node] > cp /usr/src/xterm-261* .
 - edited the "xterm-261-1.cygport" file (used vi) to _ADD_ only the 
"--disable-imake" option; which
    results in the following:
   ------------------------------
    cygconf \
        --disable-desktop \
        --disable-imake \
        --disable-narrowproto \
        --disable-setuid \
        --enable-ansi-color \
        --enable-256-color \
        --enable-broken-osc \
        --enable-broken-st \
        --enable-dabbrev \
        --enable-doublechars \
        --enable-freetype \
        --enable-i18n \
        --enable-load-vt-fonts \
        --enable-logging \
        --enable-luit --enable-mini-luit \
        --enable-tcap-query \
        --enable-toolbar \
        --enable-wide-chars \
        --with-app-defaults=$(pkg-config --variable=appdefaultdir xt) \
        cf_cv_svr4=no
   ------------------------------
 - built the package as follows:
   -- met the build prerequisites defined in the 
"xterm-261-1.cygwin.patch" file
   -- [user@node] > cygport ./xterm-261-1.cygport all
 - exited and closed all cygwin X-sessions and X-server
 - started a cygwin bash console session (via the 'Cygwin Bash Shell' 
shortcut)
 - installed the newly-built xterm package from the newly-created 
"xterm-261-1.tar.bz2"
    file as follows:
   -- [user@node] > cd /
   -- [user@node] > tar xvf ~/xterm-build/xterm-261-1.tar.bz2 --bzip2
 - started the XWin server and an xterm terminal

The result is that the scrollbar now works fine ... the scroll handle 
starts as the full height of
the window and compresses towards the bottom of the slider as the 
content scrolls off the
top of the screen.  Also, mouse button actions no longer change the size 
of the handle.

Tested only in Win7 64-bit.

I just thought this may be helpful feedback.

BTW, my sincere thanks goes out to all of the hard-working developers 
and contributors
of Cygwin!!!  Thank You! :-)

Kindly,
Ken
