There have been no changes regarding this problem.

You could try compiling the xserver with special debugging options:
get the source from cvs

$ cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/xorg login
CVS password: <hit return>
$ cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/xorg co -P -rXORG-6_8_0 xc

this will extrat the sources to the directory xc.

add this to xc/config/cf/host.def:
#define OptimizedCDebugFlags   -ggdb3 -O2 -fno-strength-reduce -DCYGDEBUG=YES 
#define BuildFonts NO
#define BuildServersOnly YES

run "make World" from the xc directory.

you can now start XWin with 
programs/Xserver/XWin.exe [the options you use normally] -logverbose 10

This should print a logmessage whenever a windows message (including the
clipboard messages) is received and some other debugging information. 
maybe this gives a clue what causes the lockup.

Any clipboard related errors should vanish if you omit the -clipboard 
parameter.
