XWin seems to only starts partway

[Bill Shaffer]

Hi:

I have just downloaded and installed the latest cygwin distribution, and I 
am seeing intermittent problems starting XWin using the startxwin.bat file 
from windows explorer.  This in on WinXPsp2.

Most of the time things start up fine; but I see the problem often enough 
that I can reproduce it within a few minutes.  When XWin fails to completely 
start up, I see:
- the black X in the system tray, but I can't right click on it for a menu
- port 6000 listening
- established connections on port 6000 (localhost to localhost)
- XWin, xhost, and xterm processes in ps -ef
- if I attempt to export my display from another server, I see the 
established connection but no X window
- if I attempt to display X from localhost, I see more extablished 
connections but no window

If I kill -9 Xwin and restart it, it usually works.

The /tmp/XWin.log from a normal working startup:
_XSERVTransmkdir: ERROR: euid != 0,directory /tmp/.X11-unix will not be 
created.

The first line in the "good" log after the "bad" log stops is a mutex_return 
- which might indicate that a mutex is never returning from somewhere and 
keeping the startup from finishing?

Any help would be appreciated.

Bill
