I am having two problems when I click the "XWin Server" item in the 
Windows "Start Menu"

1.The "Cygwin X/Server" icon appears in the notification area.But if I 
right click the notification icon, no menu appears.

2.The "X Applications Menu" (XDG Menu) icon does not appear in the 
notification area

Cygcheck.out and XWin.0.log attached.
