Hi,
I have installed Cygwin 1.7.6-1 on "Windows 7" running on a
virtual machine (VMware Workstation 6.5.4). I am using TCSH instead
of BASH and I have configured an X11 GUI which I use since 2004
with Cygwin 1.5.x (since about a year with X11R7) on Windows XP
without problems. When I use this environment with Cygwin 1.7.6, I
have the following problems. I have seen in the mailing list that
other persons have similar problems, but I have not found a solution.
Perhaps I have some additional information which can track the problem.
Sometimes I get only one xterm-window or the background color of
the root window will only be painted in the upper part or not
all. Most times I get no xterm-window, when I left-click in the
root window of the window manager "fvwm2" and choose "xterm". In
these cases I get for example the following error messages in the
original console window from Cygwin.
8 [main] fvwm 3168 exception::handle: Exception:
STATUS_ACCESS_VIOLATION
101981 [main] fvwm 3168 open_stackdumpfile: Dumping stack trace
to fvwm.exe.stackdump
8 [main] xterm 468 exception::handle: Exception:
STATUS_ACCESS_VIOLATION
1591 [main] xterm 468 open_stackdumpfile: Dumping stack trace
to xterm.exe.stackdump
I close and restart Cygwin in these cases until I get the expected
user interface with two "xterm windows". The problem remains even if
I disable "Windows Firewall". Sometimes Cygwin repaints only the upper
part of the graphical user interface when I close Cygwin to an icon and
reopen the icon. When I move with the mouse cursor over the unpainted
parts (contents of "xterm windows" or the background of the "root
window") the area under the mouse pointer will be repainted (like a
brush). Sometimes all missing parts are automatically repainted when I
execute a command. The access violation is not restricted to "xterm".

very much for any help to solve this problem in advance.
Kind regards
