Can’t run Cygwin/X as administrator on windows 7

cygwinuacwindows 7

When I run Cygwin/X as administrator, I get periodic errors when I try to run, e.g., xterm. I can get around this by running as not administrator, but I've been getting these errors when running exim as a service, so I need a better solution. Is cygwin even set up to run as administrator? Do I need to do something with UAC to enable this?

The errors I get are:

  0 [main] xterm 8352 child_copy: linked dll data write copy failed, 0x2BE000..0x2C27EC, done 0, windows pid 8844, Win32 error 487
xterm: Error 29, errno 11: Resource temporarily unavailable

and 

  0 [main] xterm 5920 exception::handle: Exception: STATUS_ACCESS_VIOLATION
741 [main] xterm 5920 open_stackdumpfile: Dumping stack trace to xterm.exe.stackdump

The stack dump is not helpful:

Exception: STATUS_ACCESS_VIOLATION at eip=6102048B
eax=00F300F8 ebx=61246E5C ecx=75530D06 edx=00334118 esi=00000000 edi=0028F9F4
ebp=61020C00 esp=0028C7C4 program=C:\cygwin\bin\xterm.exe, pid 6888, thread main
cs=0023 ds=002B es=002B fs=0053 gs=002B ss=002B
Stack trace:

End of stack trace

Thanks,

I found the solution. In response to two questions in the FAQ, I reinstalled the basic Cygwin packages, and the problem seems to have disappeared. As per the instructions in the FAQ, I stopped my Cygwin services and killed all the bash and sh jobs before reinstalling.
